Crystal structure and Hirshfeld surface analysis of N-[(2-hy­droxy­naphthalen-1-yl)(3-methyl­phen­yl)meth­yl]acetamide

The title compound, C20H19NO2, is of inter­est as a precursor to biologically active substituted quinolines and related compounds. This compound crystallizes with two independent mol­ecules (A and B) in the asymmetric unit. The dihedral angles between mean planes of the methyl­phenyl ring and the naphthalene ring system are 78.32 (6) and 84.70 (6)° in mol­ecules A and B, respectively. In the crystal, the anti­ferroelectric packing of mol­ecules A and B is of an ABBAABB type along the b-axis direction. The crystal structure features N—H⋯O, O—H⋯O and weak C—H⋯O hydrogen bonds, which link the mol­ecules into infinite chains propagating along the b-axis direction.
