✦ Synopsis

The title compound, C 30 H 32 ClNO 3 , was synthesized by the reaction of dimedone with 4-methoxybenzaldehyde and 4chlorobenzenamine in water. The dihydropyridine ring is in a boat conformation. Both cyclohexene rings adopt envelope conformations. The chlorophenyl and methoxyphenyl rings form dihedral angles of 81.31 (11) and 88.84 (12) , respectively, with the planar part of the dihydropyridine ring. The crystal packing is stabilized by weak C-HÁ Á ÁO hydrogen bonds.
