Reaction Steps
To a solution of ethyl(2RS,3RS)-3-[4-(benzyloxy)phenyl]-3-hydroxy-2-[3-(1,1,2,2-tetrafluoroethoxy)benzyl]propanoate (25.0 g, 49.4 mmol) in methanol (200 ml) was added 2N aqueous sodium hydroxide solution (49.0 ml, 98.0 mmol), and the mixture was stirred overnight at room temperature. The reaction solution was acidified with 1N hydrochloric acid and extracted with ethyl acetate (500 ml×2). The extract was washed with water and saturated brine, dried (anhydrous magnesium sulfate) and evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate). Recrystallization from ethyl acetate-hexane gave the objective substance (21 g, 89%).
