실험 절차

From the reaction of 5-methyl-2-(4-aminophenyl)-2,4-dihydro-pyrazol-3-one and ethylchloroformate (per the reaction in Example 11) yields N-(4-(4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl)-phenyl-carbamic acid ethyl ester. Subsequent reaction with 2-methoxyaniline yields N-(4-(4,5-dihydro-4-(2-methoxyanilinomethylene)-3-methyl-5-oxo-1H-pyrazol-1-yl)-phenyl)-carbamic acid ethyl ester, Mp: 212° C.
