Reaction Steps

Sodium triacetoxyborohydride (0.297 g) was added to a solution of 3-methylsulphanylpropionaldehyde (0.1 ml) and (R)-N-(2-chloro-4-aminophenyl)-2-hydroxy-2-methyl-3,3,3-trifluoropropanamide (Example 208) (0.282 g) in 1,2-dichloroethane (6 ml). The mixture was stirred for 16 hours. Saturated aqueous sodium hydrogen carbonate (25 ml) was added and the mixture was extracted with ethyl acetate (40 ml). The extracts were washed with brine (15 ml) then dried. Volatile material was removed by evaporation and the residue was purified by chromatography on a Varian Isolute silica column eluting with 25% ethyl acetate/hexane. The resulting solid was triturated with ether to give the title compound (0.089 g) as a solid. NMR: 1.54 (s, 3H), 1.78 (m, 2H), 2.05 (s, 3H), 2.55 (q, 2H), 3.09 (q, 2H), 5.93 (t, 1H), 6.54 (dd, 1H), 6.65 (s, 1H), 7.46 (m, 2H), 9.33 (s, 1H); MS (ESP−): 369.
