実験手順
To a methanol solution (5 ml) of 7N ammonia was added the ethyl[[[5-chloro-[(4-chlorophenylsulfonyl)(2,5-difluorophenyl)methyl]pyridin-2-yl]amino]sulfonyl]acetate (78 mg, 0.135 mmol) obtained in Example 283. The resulting mixture was stirred at room temperature for 3 days, followed by concentration under reduced pressure. The residue thus obtained was subjected to flash silica gel column chromatography. The fraction obtained from the methanol:methylene chloride (=1:25) eluate was concentrated under reduced pressure to give the title compound (66 mg, 0.120 mmol, 89%) as a white solid.
