Dimethyl Sulfoxide → HCID 86584558, compound

Participants

Reaction Steps

A mixture of N-{4-[(1S)-2-bromo-1-hydroxyethyl]phenyl}methanesulfonamide (which was obtained in Example 112) (1.73 g, 5.9 mmol), sodium iodide (0.88g, 5.9 mmol), sodium azide (1.53 g, 23.6 mmol), and methyl sulfoxide (15 mL) was stirred at ambient temperature for 7 days, poured into water and extracted with ethyl acetate. The organic extracts were washed with water, and dried over MgSO4. Evaporation and purification by flash chromatography (hexanes/chloroform/isopropylalcohol 5/4.5/0.5) gave an off-white solid (0.56 g, 70% yield); MS (ES) m/z: 256 (M)+; 1H NMR (400 MHz, DMSO-d6) δ 2.94 (s, 3H), 3.30 (m, 2H), 4.74 (m, 1H), 5.75 (d, 1H), 7.17 (d, 2H), 7.32 (d, 2H), 9.67 (s, 1H).
