Abstract :
The title compound, C17H12N4O3, a pyridopyrrolopyrimidine derivative, is almost planar. The nitrobenzene ring is inclined to the mean plane of the 8,9-dihydropyrido[2,3-d]pyrrolo[1,2-a]pyrimidin-5(7H)-one moiety (r.m.s. deviation = 0.023 Å) by 6.8 (1)°. In the crystal, molecules are linked via C—H⋯O and C—H⋯N hydrogen bonds, forming layers parallel to (101).
