Reaction Steps

Ethanolamine (0.014 ml) was added to a solution of (R)-N-[2-chloro-4-(2-fluoro-phenylsulphonyl)phenyl]-2-hydroxy-2-methyl-3,3,3-trifluoropropanamide (Method 63) (0.10 g) in NMP (1.5 ml) and the solution was heated at 120° C. for 18 hours then cooled. Saturated aqueous ammonium chloride solution (10 ml) was added and the mixture was extracted with ethyl acetate (2×20 ml). The organic extracts were combined, washed with brine and dried. Volatile material was removed by evaporation and the residue was purified by chromatography on a silica gel Mega Bond Elut column eluting with 0-50% ethyl acetate/hexane to give the title compound (0.074 g) as a solid. Mp 68-70° C.; NMR (CDCl3): 1.75 (s, 3H), 3.3 (q, 2H), 3.90 (m, 2H), 3.95 (brs, 1H), 6.50 (brt, 1H), 6.70 (d, 1H) 6.80 (m, 1H), 7.4 (m, 1H), 7.85 (m, 2H), 8.00 (d, 1H), 8.55 (d, 1H), 9.25 (brs, 1H); MS (ESP−): 465; EA: found: C, 46.6; H, 4.0; N, 5.8%; C18H18ClF3N2O5S requires: C, 46.31; H, 3.89; N, 6.00%.
