実験手順

A mixture of 4.0 g (16 mmol) of 2-(N-benzyl-N-methylamino)ethyl acetoacetate, 4.6 g (16 mmol) of cyclopropylmethyl 2-(3-nitrobenzylidene)acetoacetate, 1.12 ml of 28% aqueous ammonia and 40 ml of ethanol was stirred at the reflux temperature for 8 hours, and then the solvent was removed under reduced pressure. The residue was chromatographed on silica gel column to afford 3-cyclopropylmethyl 5-[2-(N-benzyl-N-methylamino)ethyl] 1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)pyridine-3,5-dicarboxylate (3.5 g, 42.1%) as yellow oil. Treatment of this oil with hydrochloric acid gave the corresponding salt.
