반응 단계
21.87 g (0.06 moles) of 3,3,5-trimethylcyclohexyl 2-(3-nitrobenzylidene)acetylacetate and 7.84 g (0.06 moles) of ethyl 3-aminocrotonate are heated under reflux in 60 ml of ethanol for 8 hours. The solution is then cooled to -5° C. to obtain 3,3,5-trimethylcyclohexyl 2,6-dimethyl-5-ethoxycarbonyl-4-(3-nitrophenyl)-1,4-dihydropyridine-3-carboxylate as yellow crystals melting--after recrystallisation in ethanol--at 125°-129° C. The yield is 37% of the theoretical yield.
