title: 3-Isopropyl-2-(4-methoxy-phen-oxy)-1-benzo-furo[3,2-d]pyrimidin-4(3H)-one.
abstract: In the title compound, C(20)H(18)N(2)O(4), all non-H atoms of the three fused rings of the benzofuro[3,2-d]pyrimidine system are almost coplanar (r.m.s. deviation 0.021 Å). The dihedral angle between the fused ring system and the benzene ring is 1.47 (12)°. Intra-molecular and inter-molecular C-H⋯O hydrogen bonds together with weak C-H⋯π inter-actions stabilize the structure.
