Diethyl 4-(1H-imidazol-2-yl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate

Abstract

In the title compound, C16H21N3O4, the 1,4-dihydropyridine ring adopts a flattened boat conformation, with the imidazole substituent in an axial orientation [dihedral angle between ring planes = 82.9 (6)°]. In the crystal structure, pairs of N—H...O and N—H...N hydrogen bonds with graph-set notation R 2 2(14) connect the molecules into chains running along the c-axis direction.
