(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-bondedR42(8) andR22(20) rings
摘要:
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 center dot center dot center dot O hydrogen bonds link the molecules into chains of edge-fused R-4(2)(8) and R-2(2)(20) rings.
