실험 절차

##STR36## 301 mg (0.763 mM) of 2-chloroethyl methyl 1,4-dihydro2,6-dimethyl-4-(3-nitrophenyl)pyridine-3,5-dicarboxylate and 155 mg (0.763 mM) of 4-(1-imidazolylmethyl)benzaldoxime were dissolved in 5 ml of dried acetonitrile, and then to the solution 58 mg (0.42 mM) of anhydrous potassium carbonate was added. After the mixture was heated under reflux for 15 hours, acetonitrile was distilled away and dichloromethane was added to the residue. After washing with water, the residue was dried over anhydrous sodium sulfate and dichloromethane was distilled away, and then the crystals were recrystallized from methanol, whereby the captioned compound was obtained. The yield was 400 mg (94%).
