Diethyl 4-(4-acetamido-phenyl)-2,6-dimethyl-1,4-dihydro-pyridine-3,5-dicarboxyl-ate.
The title compound, C(21)H(26)N(2)O(5), was unexpectedly obtained as a by-product in the reaction of ethyl acetoacetate, 4-acetamido-benzaldehyde and urea under microwave irradiation. The dihydro-pyridine ring assumes a flattened boat conformation. Inter-molecular N-H⋯O and weak C-H⋯O hydrogen bonding occurs in the crystal.
