Abstract

The title compound, C26H31N3O2S, crystallizes with two mol-ecules (A and B) in the asymmetric unit. In each case, the piperidine ring exists in a twist-boat conformation. The dihedral angle between the phenyl rings is 46.16 (12)° in mol-ecule A and 44.95 (12)° in mol-ecule B. In both mol-ecules, the allyl side chain is disordered over two orientations in a 0.649 (9):0.351 (9) ratio for mol-ecule A and 0.826 (10):0.174 (10) ratio for mol-ecule B. In the crystal, neither mol-ecule forms a hydrogen bond from its N-H group, presumably due to steric hindrance. A+A and B+B inversion dimers are formed, linked by pairs of weak C-H⋯O hydrogen bonds enclosing R 2 (2)(22) ring motifs.
