実験手順

To a solution of 1-allyl-N-(4-fluoro-5-((2-fluoro-4-iodophenyl)amino)benzo[d][1,2,3]thiadiazol-6-yl)cyclopropane-1-sulfonamide (50 mg, 0.09 mmol) in THF (5 mL) was added N-methylmorpholine-N-oxide (12 mg, 0.09 mmol) followed by osmium tetraoxide (5 mg, 0.02 mmol) and water (0.5 mL). The resultant was stirred at room temperature overnight. The mixture was concentrated and then diluted with ethyl acetate. The organic layer was washed with water, saturated NaHCO3 (aq.) and brine sequentially, dried over Na2SO4, filtered and concentrated to give a residue, which was purified by flash chromatography on silica gel to give the product as white solid (30 mg, 56.5% yield). 1H NMR (400 MHz, CDCl3): δ 8.26 (s, 1H), 7.67-7.64 (d, 2H), 7.32 (m, 1H), 7.03 (s, 1H), 6.85 (s, 1H), 4.40-4.26 (m, 2H), 4.20-4.10 (m, 1H), 3.75-3.60 (m, 1H), 3.60-3.50 (m, 1H), 2.62-2.50 (m, 2H), 0.92-0.82 (m, 4H). MS APCI (+) m/z: 583.5, [M+H].
