Abstract
In the title compound, C24H25NO, the phenyl and diphenylmethanol substituents are syn to each other. The pyrrolidine ring has an envelope conformation with the flap atom being the C atom bearing the phenyl substituent. The hydroxy group forms an intramolecular hydrogen bond with the pyrrolidine N atom, and the phenyl rings lie to same side of the molecule. The crystal packing features C—H⋯π interactions. Two slightly displaced co-planar orientations were found for one of the phenyl rings; the major component had a site-occupancy factor of 0.782 (15).
