In the mol-ecule of the title compound, C21H15N 3O, the 10H-9-oxa-1,3-diaza-anthracene 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, mol-ecules 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⋯π inter-actions.
