Reaktionsschritte

434 mg (1 mM) of 4-(3-nitrophenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylic acid monocinnamyl ester, 226 mg (1.1 mM) of dicyclohexylcarbodiimide, 122 mg (1 mM) of 4-dimethylaminopyridine and 127 mg (1.2 mM) of 2-ethylthioethanol were dissolved in 10 ml of dichloroethane, and refluxed for 2 hours. After the reaction mixture was chilled, insoluble matters were filtered off. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography to obtain 511 mg of cinnamyl 2-ethylthioethyl 4-(3-nitrophenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate (yield 98%).
