Participants

Reaction Steps

To a mixture of ethyl 3-[4-({4′-[2-(diethylamino)ethoxy]-2′,6′-dimethylbiphenyl-3-yl}methoxy)-2-fluorophenyl]propanoate (0.62 g, 1.18 mmol), methanol (5 mL) and tetrahydrofuran (10 mL) was added 1 N aqueous sodium hydroxide solution (2.4 mL) at room temperature with stirring and the mixture was stirred at the same temperature for 2 hrs. The reaction mixture was neutralized with 1 N hydrochloric acid, diluted with ethyl acetate, washed with saturated brine, dried and concentrated under reduced pressure. The residue was purified by preparative HPLC to give a colorless oil. The oil was dissolved in ethyl acetate, neutralized with saturated aqueous sodium hydrogen carbonate, washed with water and saturated brine, dried and concentrated under reduced pressure. The residue was dissolved in ethyl acetate and 4 N hydrogen chloride-ethyl acetate solution was added. The precipitated crystals were collected by filtration, washed and dried to give the title compound (0.20 g, yield 32%) as colorless crystals.
