2-(4-Methoxy­phen­oxy)-1,9-diphenyl-1,9-dihydro­purin-6-one

The title compound, C24H18N4O3, has a planar bicyclic imidazolo[5,4-d]pyrimidine core. The planes of the phenyl and methoxy­phen­oxy substituents form substantial (>30°) dihedral angles with the imidazolopyrimidine plane. Inter­molecular C—H⋯O inter­actions link the mol­ecules into infinite chains running along the a axis of the crystal structure.
