反应详情

Methyl 2-(2-fluorophenyl)propanoate (26.2 g, 0.144 mol) was dissolved in THF (325 ml) and LiOH (1 M, 173 ml) added. The reaction mixture was stirred at room temperature for 2.5 h, before diluting with diethyl ether and extracting with water and 1N NaOH. The aqueous layer was acidified and extracted with ethyl acetate (×2). The organic extract was washed with brine, dried and evaporated to yield 2-(2-fluorophenyl)propanoic acid (22.5 g, 100%) as an oil.
