실험 절차

To a methylene chloride solution (10.0 ml) of [5-chloro-4-[(2,5-difluorophenyl)-(4-fluorophenylsulfonyl)methyl]pyridin-2-yl]amine (114 mg, 0.276 mmol) was added pyridine (440 μl, 5.5 mmol). To the resulting mixture was added methanesulfonyl chloride (addition of 77 μl once a day for 3 days, 230 μl in total, 3.0 mmol). The resulting mixture was stirred for 4 days in total. The reaction mixture was concentrated under reduced pressure. The residue thus obtained was purified by silica gel chromatography (hexane:ethyl acetate=2:1), followed by crystallization in ether to give the title compound (51 mg, 38%) as a white solid.
