実験手順

A mixture of 0.40 g of 2-[1-(3-chloro-2-pyridinyl)-3-trifluoromethyl-1H-pyrazol-5-yl]-8-methyl-4H-3,1-benzoxazine-4-one, 0.09 ml of hydrazine monohydrate and 20 ml of tetrahydrofuran was stirred at room temperature for 3 hours. Water was poured into the reaction mixture, and the mixture was extracted with ethyl acetate three times. The organic layers were combined, washed with an aqueous saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to obtain 0.26 g of 1-(3-chloro-2-pyridinyl)-N-[2-(hydrazinocarbonyl)-6-methylphenyl]-3-trifluoromethyl-1H-pyrazole-5-carboxamide of the formula:
