実験手順

To a solution (5 mL) of tert-butyl{[5-{2-fluoro-3-[(hydroxyimino)methyl]phenyl}-1-(pyridin-3-ylsulfonyl)-1H-pyrrol-3-yl]methyl}methylcarbamate (150 mg) in tetrahydrofuran were added triethylamine (93 mg) and methanesulfonyl chloride (84 mg) at room temperature. The reaction mixture was stirred at 70° C. for 8 hr, and cooled to room temperature. Water was added and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent:hexane-ethyl acetate=8:1→3:1) to give the title compound as a pale-yellow oil (yield 106 mg, 73%).
