title: 1-[(2-Hy-droxy-phen-yl)(pyrrolidin-1-yl)-meth-yl]naphthalen-2-ol N,N-dimethyl-formamide monosolvate.
abstract: The title compound, C(21)H(21)NO(2)·C(3)H(7)NO, was synthesized by solvent-free one-pot three-component reaction of naphthalen-2-ol, 2-hy-droxy-benzaldehyde and pyrrolidine. The dihedral angle between the naphthalene ring system and the benzene ring is 77.74 (6)°. The pyrrolidine ring assumes an envelope conformation. An intra-molecular O-H⋯N and an inter-molecular O-H⋯O hydrogen bond are observed.
