Hydrochloric Acid → HCID 86593229, compound

Participants

Reaction Steps

To a solution of zinc chloride (5.39 g, 39.6 mmol) in diethyl ether (100 ml) was added sodium borohydride (3.00 g, 79.1 mmol) and the mixture was stirred at room temperature for 30 min. The insoluble material was filtered off. To the filtrate was added a solution of ethyl 3-(4-fluorophenyl)-3-oxo-2-((4-(phenyloxy)phenyl)methyl)propionate (7.76 g, 19.8 mmol) in diethyl ether (50 ml) and the mixture was stirred at room temperature for 30 min. 1N Hydrochloric acid was added to the reaction solution under ice-cooling for quenching, water (200 ml) was added, and the mixture was extracted with ethyl acetate (300 ml×2). The extract was washed with water and saturated brine, dried over anhydrous magnesium sulfate and evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=4:1-1:1) to give ethyl (2RS,3RS)-3-(4-fluorophenyl)-3-hydroxy-2-((4-(phenyloxy)phenyl)methyl)propionate (6.66 g, 85%) as a colorless oil.
