2-Diisopropyl­amino-3-phenyl­benzo[4,5]furo[3,2-d]pyrimidin-4(3H)-one

In the title compound, C₂₂H₂₃N₃O₂, the three fused rings of the benzofuro[3,2-d]pyrimidine system are almost coplanar. The packing of the mol­ecules in the crystal structure is mainly due to π–π and inter­molecular C—H...O hydrogen-bonding inter­actions.
