Participants

Reaction Steps

To a solution of ethyl (2RS,3RS)-3-(4-fluorophenyl)-3-hydroxy-2-{3-[(trifluoromethyl)thio]benzyl}propanoate (5.30 g, 13.17 mmol) in methanol (150 ml) was added 2N aqueous sodium hydroxide solution (13.2 ml, 26.4 mmol), and the mixture was stirred overnight at room temperature. After the reaction solution was concentrated, 1N hydrochloric acid was added. The mixture was acidified and extracted with ethyl acetate (200 ml×2). The extract was washed with water and saturated brine, dried (anhydrous magnesium sulfate) and evaporated under reduced pressure. The residue was recrystallized from ethyl acetate-hexane to give the objective substance (3.98 g, 81%).
