A monoclinic polymorph of 4-(2H-1,3-benzodioxol-5-yl)-1-(4-methyl-phen-yl)-1H-pyrazol-5-amine.

The title compound, C17H15N3O2, is a monoclinic polymorph (P21/c with Z' = 1) of the previously reported triclinic (P-1 with Z' = 2) form [Gajera et al. (2013 ▸). Acta Cryst. E69, o736-o737]. The mol-ecule in the monoclinic polymorph features a central pyrazolyl ring with an N-bound p-tolyl group and a C-bound 1,3-benzodioxolyl fused-ring system on either side of the C atom bearing the amino group. The dihedral angles between the central ring and the N- and C-bound rings are 50.06 (5) and 27.27 (5)°, respectively. The angle between the pendent rings is 77.31 (4)°, indicating the mol-ecule has a twisted conformation. The five-membered dioxolyl ring has an envelope conformation with the methyl-ene C atom being the flap. The relative disposition of the amino and dioxolyl substituents is syn. One of the independent mol-ecules in the triclinic form has a similar syn disposition but the other has an anti arrangement of these substituents. In the crystal structure of the monoclinic form, mol-ecules assemble into supra-molecular helical chains via amino-pyrazolyl N-H⋯N hydrogen bonds. These are linked into layers via C-H⋯π inter-actions, and layers stack along the a axis with no specific inter-actions between them.

Chemical context

It is the broad range of biological activities, such as anti-depressant, anti-n class="Disease">anxiety, aclass="Chemical">nti-fuclass="Chemical">ngal, aclass="Chemical">nti-bacterial, aclass="Chemical">nti-class="Chemical">n class="Disease">diabetic, anti-cancer, etc. (Tanitame et al., 2004 ▸; Chimenti et al., 2006 ▸; Ding et al.,2009 ▸; Shen et al., 2011 ▸; Deng et al., 2012 ▸), that continues to inspire inter­est in compounds containing the amino-substituted pyrazole unit. It was in this context that the crystal structure of 4-(2H-1,3-benzodioxol-5-yl)-1-(4-methyl­phen­yl)-1H-pyrazol-5-amine (I) was originally determined (Gajera et al., 2013 ▸). Subsequently, during scale up, crystals of the monoclinic form were isolated from recrystallization of (I) from ethyl acetate, the same solvent system that afforded the original triclinic polymorph. Herein, the crystal and mol­ecular structures of the monoclinic form of (I), hereafter (mI), are described and compared with the triclinic polymorph, (tI).

Structural commentary

The mol­ecule in (n class="Chemical">mI), Fig. 1 ▸, comprises a ceclass="Chemical">ntral aclass="Chemical">nd almost placlass="Chemical">nar class="Chemical">n class="Chemical">pyrazolyl ring (r.m.s. deviation of the five atoms = 0.0043 Å) flanked by an N-bound p-tolyl group and a C-bound 1,3-benzodioxolyl fused ring system. In the latter, the five-membered dioxolyl ring adopts an envelope conformation with the methyl­ene-C17 atom being the flap; the C17 atom lies 0.318 (2) Å out of the least-squares plane defined by the O1, O2, C14 and C15 atoms (r.m.s. deviation = 0.0005 Å). The dihedral angles between the central ring and the N- and C-bound six-membered rings are 50.06 (5) and 27.27 (5)°, respectively. The dihedral angle between the six-membered rings is 77.31 (4)°, indicating an overall twisted arrangement. In general terms, the relative disposition of the amino and dioxolyl substituents may be described as being syn.

These differences in mol­ecular conformations are highlighted in Fig. 2 ▸. The syn/anti distinction is quite clear from this overlap diagram where the dioxolyl ring obviously occupies a different position in the second independent mol­ecule of (tI, blue image). Also evident from Fig. 2 ▸ are variations in the relative dispositions of six-membered rings. These variations are qu­anti­fied in Table 1 ▸.

The pattern was analyzed with X’Pert HighScore Plus (PANalytical, 2009 ▸). This analysis indicated that the ratio of (mI) to (tI) in the overall sample was 49.1:50.9. This distribution suggests that effectively in the sample there is a 3:1 ratio of mol­ecules with a syn disposition of the amino and dioxolyl substituents to those with a trans arrangement.

Supra­molecular features

The most notable feature of the crystal packing in (n class="Chemical">mI) is the formatioclass="Chemical">n of supra­molecular helical chaiclass="Chemical">ns aligclass="Chemical">ned aloclass="Chemical">ng the b axis aclass="Chemical">nd mediated by aclass="Chemical">n class="Chemical">mino–pyrazolyl N—H⋯N hydrogen bonds, Fig. 3 ▸ and Table 2 ▸. The chains are consolidated into layers in the bc plane by pyrazol­yl–tolyl C10—H⋯π and methyl­ene–benzo-C6 C17—H⋯π inter­actions, Table 2 ▸. The layers inter-digitate along the a axis whereby the dioxolyl rings face each other, Fig. 4 ▸. The C—H⋯O inter­actions are at distances beyond the standard criteria (Spek, 2009 ▸). In the packing scheme just described, no specific role is found for the second amino-H2N atom. To a first approximation, the mode of association between mol­ecules in (tI) is similar in that supra­molecular chains are formed. These comprise alternating independent mol­ecules a and b that are connected by amino–pyrazolyl N—H⋯N hydrogen bonds. The difference is that in (tI), the chains have a zigzag topology. Chains in (tI) are connected by C—H⋯O and C—H⋯π inter­actions.

The C—H⋯π inter­actions in (mI) are indicated by both diminutive spots and light-red regions on the surface. These are also apparent in (tI) with additional features arising from the C—H⋯O contacts, Fig. 5 ▸. The fingerprint plots (Rohl et al., 2008 ▸) were also calculated and enabled a delineation of the relative contribution of the different inter­molecular contacts to the respective crystal structures. These contributions are illustrated graphically in Fig. 6 ▸. Despite the different modes of association between the respective mol­ecules, to a first approximation the relative contributions to the surfaces are similar.

Database survey

A search of the Cambridge Structural Database (Groom & Allen, 2014 ▸), revealed there are no direct analogues of (I), i.e. 1,3 n class="Chemical">N- aclass="Chemical">nd C-disubstituted species. There are four examples of 1,3,4 tris­ubstituted aclass="Chemical">nalogues (Abu Thaher et al., 2012 ▸; aclass="Chemical">nd refereclass="Chemical">nces thereiclass="Chemical">n).

Synthesis and crystallization

The title compound was synthesized according to the same synthetic process as described in the original report (Gajera et al., 2013 ▸). Single crystals suitable for X-ray measurements in the form of light-brown prisms were obtained from its n class="Chemical">ethyl acetate solutioclass="Chemical">n at room temperature.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
