Reaction Steps

Sodium methanethiolate (49.5 mg) was added to a solution of (R)-N-[2-chloro-4-(2-fluorophenylsulphonyl)phenyl]-2-hydroxy-2-methyl-3,3,3-trifluoropropanamide (Method 63) (0.15 g) in NMP (1.5 ml) and the mixture was heated at 120° C. for 18 hours then cooled. Saturated aqueous ammonium chloride solution (15 ml) was added and the mixture was extracted with ethyl acetate (2×50 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 0-20% ethyl acetate/hexane to give the title compound (0.10 g) as a solid. NMR: (CDCl3): 1.75 (s, 3H), 2.4 (s, 3H), 3.6 (brs, 1H), 7.3 (t, 1H), 7.35 (t, 1H), 7.55 (m, 1H), 7.9 (dd, 1H), 8.05 (d, 1H), 8.25 (dd, 1H), 8.6 (d, 1H), 9.25 (brs, 1H); MS (ESP−): 452.
