(4RS,1'RS)-Methyl 1-Phenyl-2-piperidinoethyl 1,4-Dihydro-2,6-dimethyl-4-(2-thienyl)pyridine-3,5-dicarboxylate Methanol Solvate, C₂₇H₃₂N₂O₄S.1.5CH₄O

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 pseudoaxial 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.
