実験手順
m-Chloroperoxybenzoic acid (50%, 0.293 g) was added to a solution of (R)-N-[2-chloro-4-(2-methylsulphanylphenylsulphonyl)phenyl]-2-hydroxy-2-methyl-3,3,3-trifluoropropanamide (Example 1) (0.384 g) in DCM (40 ml). The mixture was stirred at ambient temperature for 6 hours then washed with saturated aqueous sodium hydrogen carbonate solution (3×100 ml), water (100 ml) and brine and then dried. Volatile material was removed by evaporation and the residue was purified by chromatography on a silica gel Mega Bond Elut column eluting with 50-70% ethyl acetate/hexane to give the title compound (0.26 g) as a solid. Mp 118-120° C.; NMR (CDCl3): 1.70 (s, 3H), 3.0 (m, 3H), 4.85 (brs, 1H), 7.75 (t, 1H), 7.85 (m, 2H), 8.0 (m, 1H), 8.15 (d, 1H), 8.3 (d, 1H), 8.65 (dd, 1H), 9.40 (brs, 1H); MS (ESP−): 468; EA: found: C, 44.3; H, 3.7; N, 2.6%; C17H15ClF3NO5S2.0.125C4H8O2.0.3C4H10O requires: C, 44.64; H, 3.81; N, 2.78%.
