(E)-3-{2-amino-4-ethoxy-6-[N-(4-methoxyphenyl)-N-methylamino]pyrimidin-5-yl}-1-phenylprop-2-en-1-one: a boat-shaped pyrimidine ring and a chain of hydrogen-bonded R4(2)(8) and R2(2)(20) rings.

In the title compound, C23H24N4O3, the pyrimidine ring adopts an almost perfect boat conformation, and the bond distances provide evidence for some polarization of the molecular-electronic structure. Two independent N-H...O hydrogen bonds link the molecules into chains of edge-fused R2(4)(8) and R2(2)(20) rings.
