Abstract

In the title compound, C21H25NO4, the dihydropyridine ring adopts a flattened boat conformation. The N atom and the sp3 C atom deviate in the same direction from the mean plane of the other four C atoms, by 0.269 (6) and 0.111 (6) Å, respectively. This mean plane is inclined to the 4-methoxyphenyl ring by 87.3 (5)°. The cyclohexenone ring has a sofa conformation with the C atom bearing the methyl groups deviating from the mean plane through the other five C atoms by 0.628 (6) Å. There is a short C—H...O hydrogen bond in the molecule. In the crystal, molecules are linked by an N—H...O hydrogen bond to form chains propagating along the c-axis direction.
