(4RS,1'RS)-methyl 1-phenyl-2-piperidino-ethyl 1,4-dihydro-2,6-dimethyl-4-(2-thienyl)pyridine-3,5-dicarboxylate methanol solvate, C27H32N2O4S.1.5.CH4O

The two independent molecules in the asymmetric unit have similar conformations. The 4-thienyl-1,4-dihydropyridine moieties adopt a flat boat conformation commonly observed for 4-aryl-1,4-dihydropyridine derivatives with the 4-thienyl group in a pseudo-axial orientation, The thienyl and phenyl rings are perpendicular to each other, The six methanol molecules in the unit cell stabilize the crystal structure through intermolecular hydrogen bonds involving the N atoms of the dihydropyridine and the piperidine rings of both molecules.
