Reaction Steps

This amine was dissolved in CH2Cl2 (5 mL) and treated with 2,2,2-trifluoroethylsulfamoyl chloride (91 mg, 0.45 mmol) and Et3N (63 μL, 0.45 mmol) and stirred at RT for 30 min. The solvent was evaporated under reduced pressure and the residue purified by silica chromatography eluting with 2% MeOH/CH2Cl2 to yield the title sulfamide as a colourless gum (18 mg, 23% over 2 steps). 1H NMR (CDCl3, 500 MHz) δ 7.80-7.76 (1H, s), 7.65 (1H, d, J=7.8 Hz), 7.38 (1H, t, J=7.8 Hz), 7.23 (1H, d, J=7.8 Hz), 7.18-7.10 (2H, m), 6.98 (2H, t, J=8.7 Hz), 6.35 (1H, s), 4.66-4.56 (2H, m), 4.38-4.28 (1H, m), 3.69 (3H, s), 3.53-3.42 (1H, m), 3.42-3.30 (1H, m), 3.02-2.84 (4H, m), 1.62-1.52 (3H, m). MS (ES+) C22H24F4N4O2S requires: 484, found: 485 (M+H+).
