실험 절차

To a mixture of 0.26 g of N,N′-dimethylhydrazine dihydrochloride, 2 ml of water, 0.5 g of potassium carbonate and 10 ml of N,N-dimethylformamide was added 0.20 g of 2-[3-bromo-1-(3-chloro-2-pyridinyl)-1H-pyrazol-5-yl]-8-methyl-6-nitro-4H-3,1-benzoxazine-4-one. The resulting mixture was stirred at room temperature for 2 hours. The reaction mixture was poured into water, and extracted with ethyl acetate three times. The organic layers were combined, washed successively with water and an aqueous saturated sodium chloride solution, dried over anhydrous sodium sulfate, and concentrated under reduced pressure to obtain 3-bromo-1-(3-chloro-2-pyridinyl)-N-[2-(N,N′-dimethylhydrazinocarbonyl)-6-methyl-4-nitrophenyl]-1H-pyrazole-5-carboxamide of the formula:
