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 angstrom) by 6.8 (1)degrees. In the crystal, molecules are linked via CH center dot center dot center dot O and C-H center dot center dot center dot N hydrogen bonds, forming layers parallel to (101).
