Tetrahydrofuran → 1-(2,3-Dihydroxypropyl)-N-(6-ethyl-3,4-difluoro-2-(2-fluoro-4-iodophenylamino)phenyl)cyclopropane-1-sulfonamide

1-Allyl-N-(3,4-difluoro-2-(2-fluoro-4-iodophenylamino)-6-methylphenyl)cyclopropane-1-sulfonamide (70 mg, 0.13 mmol) and 4-methylmorpholine N-oxide (15 mg, 0.13 mmol) was dissolved in THF (2 mL). Osmium tetroxide was added at room temperature (0.013 mmol) 0.075 mL, 4% in H2O) and the reaction mixture was stirred at room temperature for 16 hours. EtOAc was added, the organic phase was washed with water, dried (MgSO4) and concentrated under reduced pressure. The residue was purified over silica gel chromatography (eluants: EtOAc/MeOH) to obtain the titled product. 1H NMR (300 MHz, CDCl3): δ 7.38 (dd, J=2.1 & 10.8 Hz, 1H), 7.27 (m, 2H), 7.12 (br s, 6.91 (dd, J=8.1 & 10.8 Hz, 1H), 6.69 (br s, 1H), 6.36 (dt, J=4.8, 8.7 & 13.5 Hz, 1H), 4.00 (m, 1H), 3.62 (dd, J=3.6 & 10.5 Hz, 1H), 3.47 (br m, 2H), 2.81 (q, 2H), 2.40 (dd, J=10.2 & 15.9 Hz, 1H), 1.73 (br m, 2H), 1.58 (m, 1H), 1.43 (m, 1H), 0.94 (m, 2H).
