Reaction Steps
To an acetic acid (2 ml) solution of [5-chloro-4-[(4-chlorophenylsulfonyl)(2,5-difluorophenyl)methyl]pyridin-2-yl]acetonitrile (113 mg, 0.25 mmol) was added a mixture of water (2 ml) and concentrated sulfuric acid (2 ml) at room temperature. The resulting mixture was stirred at 100° C. for 2 hours. After the reaction mixture was cooled to room temperature, water was added thereto. The resulting mixture was extracted with dichloromethane. The organic layer was dried over anhydrous sodium sulfate, and filtered. The filtrate was concentrated under reduced pressure. The residue thus obtained was washed with a mixed solvent of diethyl ether/hexane and then, collected by filtration to give the title compound (101 mg, 0.21 mmol, 86%) as a white solid.
