Procedure

A solution of Oxone (1.44 g) in water (15 ml) was added to a solution of (R)-N-{2-chloro-4-(2-propenylsulphanyl)phenyl}-2-hydroxy-2-methyl-3,3,3-trifluoropropanamide (Example 407) (0.389 g) in methanol (15 ml). The mixture was stirred for 1.5 hours. Water (50 ml) was added and the mixture extracted into ethyl acetate (100 ml) and dried. Volatile material was removed by evaporation and the residue purified on a silica gel Mega Bond Elut column eluting with 20-30% ethyl acetate/iso-hexane to give the title compound as a foam (0.180 g). NMR: 1.61 (s, 3H), 4.18 (d, 2H), 5.18-5.32 (m, 2H) 5.61-5.75 (m, 1H), 7.82-7.85 (m, 1H), 7.98 (s, 1H), 8.01 (s, 1H), 8.33 (d, 1H), 9.91 (s, 1H); (ESP−): 370.
