Procedure

To an ethanol (5 ml) solution of t-butyl[4-[(4-chlorophenylsulfonyl)(2,5-difluorophenyl)methyl]-5-fluoropyridin-2-yl]carbamate (170 mg, 0.331 mmol) was added concentrated hydrochloric acid (5 ml). The resulting mixture was stirred at room temperature for 2 hours. The reaction mixture was concentrated under reduced pressure. To the residue thus obtained was added a saturated aqueous solution of sodium bicarbonate, followed by extraction with ethyl acetate. The organic layer was washed with brine, dried over magnesium sulfate, and concentrated under reduced pressure. The residue thus obtained was recrystallized from hexane:ethyl acetate to give the title compound (110 mg, 0.266 mmol, 81%) as a pale violet powder.
