The title compound, CHNO, is of inter-est as a precursor to biologically active substituted quinolines and related compounds. This compound crystallizes with two independent mol-ecules ( and ) in the asymmetric unit. The dihedral angles between mean planes of the methyl-phenyl ring and the naphthalene ring system are 78.32 (6) and 84.70 (6)° in mol-ecules and , respectively. In the crystal, the anti-ferroelectric packing of mol-ecules and is of an type along the -axis direction. The crystal structure features N-H⋯O, O-H⋯O and weak C-H⋯O hydrogen bonds, which link the mol-ecules into infinite chains propagating along the -axis direction.
