In the molecule of the title compound, C21H15N3O, the 10H-9- oxa-1,3-diazaanthracene ring system is slightly bent, with dihedral angles of 3.99 (6) and 4.80 (6)' between the pyran ring and the pyrimidine and benzene rings, respectively. This ring system makes a dihedral angle of 85.23 (3)' with the naphthalene plane. In the crystal packing, molecules are linked by N—H...N hydrogen bonds into chains along the a axis and these chains are stacked along the b axis. The crystal is further stabilized by weak C—H...N and C—H... interactions.
