Dimethyl 4-(3-hydroxy-phen-yl)-2,6-dimethyl-1,4-dihydro-pyridine-3,5- dicarboxyl-ate

Abstract

The 1,4-dihydro-pyridine ring in the title compound, C17H 19NO5, has a flattened-boat conformation, and the benzene ring is almost orthogonal to it [dihedral angle = 82.98 (12)°]. The hydr-oxy group is disordered over two positions in a 0.780 (4):0.220 (4) ratio. In the crystal, hydrogen-bonding inter-actions of the type Na - H⋯Oc and Oh - H⋯Oc (a = amine, c = carbonyl and h = hydr-oxy) link the mol-ecules into a three-dimensional network.
