実験手順

3-(4-chlorophenyl)-4-carbomethoxy-4-methyl-4,5-dihydro-1H-pyrazole hydrochloride (10 mmole), triethylamine (20 mmole), methylene chloride (30 ml and 3,5-dimethylisoxazole-4-yl isocyanate (Maybridge Chemical Co. Ltd.) (10 mmole) were reacted by stirring at room temperature for 30 minutes. The reaction mixture was then washed twice with water, dried with magnesium sulfate concentrated giving a 95% yield of N-(3,5-dimethylisoxazol-4-yl)-3-(4-chlorophenyl)-4-carbomethoxy-4-methyl-4,5-dihydro-1H-pyrazole-1-carboxamide mp 214°-216° C. NMR data was consistent with the structure.
