Abstract: In the title compound, C₂₁H₂₁Cl₂NO₂, the piperidine ring adopts a distorted boat conformation. The two phenyl rings are approximately perpendicular to each other, with a dihedral angle of 86.12 (7)°. Molecules are linked into centrosymmetric dimers by pairs of bifurcated C-HO hydrogen bonds, forming R₂²(10) and R₂²(14) ring motifs, and an intramolecular C-HO link also occurs.
