실험 절차
A mixture of 0.60 g (1.7 mmol) of 1-ethyl-4-(2,3-dichloro-4-methylsulfonylbenzoyl)-5-hydroxypyrazole and 8 mL of 40 percent aqueous dimethylamine was placed in a pressure reactor and heated at 110° C. for 24 hours. It was then allowed to cool and was concentrated by evaporation under reduced pressure. The residue was dissolved in dichloromethane and the solution obtained was washed with 1N aqueous hydrochloric acid, dried over sodium sulfate, and concentrated by evaporation under reduced pressure to obtain about 0.50 g of a yellow foam. This was crystallized from ethanol to obtain, after drying for 24 hours at 50° C., 0.17 g of the title compound as an off-white solid melting at 227°-228° C. with decomposition.
