Reaction Steps
To a suspension of aluminum chloride (1.28 g) in tetrahydrofuran (15 mL) was slowly added lithium aluminum hydride (364 mg) at 0° C., and the mixture was stirred at the same temperature for 15 min. To the obtained suspension was added dropwise a solution of 5-[(3-bromophenyl)thio]-1-(2,5-difluorophenyl)-N-methyl-1H-pyrazole-3-carboxamide (1.35 g) in tetrahydrofuran (7 mL) at 0° C., and the mixture was stirred at room temperature for 1 hr. A 8 mol/L aqueous sodium hydroxide solution was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with saturated aqueous sodium hydrogen carbonate solution, water and saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure to give the title compound as a yellow oil (yield 1.18 g, 90%).
