実験手順

A solution of (S)-(3-{3-[[2-chloro-3-(trifluoromethyl)benzyl](2-phenyl-propyl)amino]propoxy}-phenyl)acetic acid methyl ester (0.6 g, 1.1 mmol) in THF (9 ml) and water (6 ml) was treated with aqueous LiOH (1.0 N, 1.0 ml, 1.0 mmol). After stirring at RT for 2 h, additional LiOH (1.0 ml, 11.0 mmol) was added and stirring was continued for 2 h. The reaction was neutralized with acetic acid and poured into water and ethyl acetate. The layers were separated and the aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate and concentrated in vacuo. The crude mixture was purified by HPLC to give the title compound as an oil (0.4 g, 75%). MS (ESI) 520.2 (M+H)+.
