Abstract

In the title compound, C21H16N2O2, the naphthalene fragment is twisted slightly, as indicated by the dihedral angle of 3.2 (2)° between the two six-membered rings. The pendant 4-methoxyphenyl ring makes a dihedral angle of 86.08 (6)° with the central six-membered ring of the 4H-benzo[g]chromene ring system. In the crystal, molecules are linked by pairs of N—H⋯N hydrogen bonds, forming inversion dimers which are linked into chains propagating in the b-axis direction by N—H⋯O hydrogen bonds.
