Abstract

In the title compound, C(21)H(25)Cl(2)NO, the dihedral angle between the two benzene rings is 33.18 (11)°. The five-membered ring adopts an envelope conformation. There is an intra-molecular O-H⋯N hydrogen bond. In the crystal, mol-ecules are linked by weak N-H⋯Cl hydrogen bonds, forming a helical chain along the c axis.
