title: Diethyl 2,6-dimethyl-4-p-tolyl-1,4-dihydro-pyridine-3,5-dicarboxyl-ate.
abstract: In the title compound, C(20)H(25)NO(4), the 1,4-dihydro-pyridine ring adopts a flattened-boat conformation and forms a dihedral angle of 89.77 (8)° with the benzene ring. Inter-molecular N-H⋯O hydrogen bonds result in the formation of extended chains parallel to the b axis.
