(E)-Ethyl 2-cyano-3-(2,4-dimeth-oxy-phen-yl)prop-2-enoate.

The C=C bond in the title compound, C(14)H(15)NO(4), is in an E configuration. With the exception of the methyl C atoms, the non-H atoms of the mol-ecule all lie approximately on a plane (r.m.s. deviation = 0.096 Å). π-π stacking is observed between parallel benzene rings of adjacent mol-ecules, the centroid-centroid distance being 3.7924 (8) Å.
