3-Isopropyl-2-(4-methoxyphenoxy)-1-benzofuro[3,2-d]pyrimidin-4(3H)-one

In the title compound, C20H18N2O4, 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)°. Intramolecular and intermolecular C—H⋯O hydrogen bonds together with weak C—H⋯π interactions stabilize the structure.
