반응 단계

2-(Methylthio)-4-(1-tosyl-5-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidine-5-carbonitrile (150 mg, 0.31 mmol) was dissolved in dichloromethane at room temperature. Meta-chloroperbenzoic acid (110 mg, 0.64 mmol) was added in one portion and the reaction was stirred for 5 minutes. Pentafluorophenol (285 mg, 1.55 mmol) was added and the solution was stirred at room temperature for 3 hours. The crude mixture was washed with a diluted solution of sodium bicarbonate and brine. The organic phase was dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified on silica gel by flash column chromatography to afford the title compound as a solid (60 mg, 31% yield).
