title: 1,1'-[4-(4-Methoxy-phen-yl)-2,6-dimethyl-1,4-dihydro-pyridine-3,5-di-yl]diethanone.
abstract: In the title compound, C(18)H(21)NO(3), which belongs to the family of calcium channel blockers, the dihydropyridine ring assumes a flattened boat conformation. The two carbonyl units adopt a synperiplanar conformation with respect to the double bonds in the dihydro-pyridine ring. The methoxy-phenyl ring is almost perpendicular to the prydine ring [dihedral angle = 89.01 (7)°]. In the crystal, the mol-ecules are connected by inter-molecular N-H⋯O hydrogen bonds.
