Reaction Steps

A mixture of (R)-N-[2-chloro-4-(4-methylphenylsulphonamido)phenyl]-2-hydroxy-2-methyl-3,3,3-trifluoropropanamide (Example 356) (0.137 g), anhydrous potassium carbonate (0.043 g) and iodomethane (0.038 ml) in acetone (8 ml) was stirred for 64 hours. Volatile material was removed by evaporation and the residue was dissolved in ethyl acetate, washed with water and brine then dried. Volatile material was removed by evaporation and the residue was purified by elution through a Varian Isolute silica 10 g column with 30% ethyl acetate/hexane as eluent to give the title compound (0.079 g). NMR: 1.60 (s, 3H), 2.38 (s, 3H), 3.11 (s, 3H), 7.11 (d, 3H), 7.32 (s 1H), 7.43 (m, 4H), 7.94 (d, 1H), 9.67 (brs, 1H); MS (ESP−): 449.
