YieldReaction ConditionsOperation in experiment
91% 8.1/(4-bromo-2-fluorophenyl)acetic acid; 0.09 g of lithium hydroxide monohydrate is added to 0.37 g (1.4 mmol) of ethyl ester of (4-bromo-2-fluorophenyl)acetic acid in solution in 8 ml of a solvent mixture THF/methanol/water (1/1/1), and the reaction mixture is stirred for 3 h at room temperature. The reaction mixture is acidified with 1N HCl solution, then extracted with dichloromethane (20 ml). The organic phases are combined, dried over Na2SO4, filtered and concentrated under reduced pressure. 0.3 g of product is obtained in the form of gum and is used without purification in the next stage. Yield 91%.

To the reaction mixture, 1 N hydrochloric acid was added, followed by extraction with methylene chloride three times. The organic layer was washed with a saturated aqueous solution of sodium bicarbonate and brine in this order and then dried over anhydrous sodium sulfate. After filtration and concentration under reduced pressure, the residue obtained was purified by silica gel column chromatography (Yamazen Corp., n-hexane/ethyl acetate=(100/0->87/13) to obtain the title compound (1.96 g, yield: 87.5%) as a solid. 1H-NMR (CDCl3) δ: 7.27-7.24 (2H, m), 7.18-7.14 (1H, m), 4.17 (2H, q, J=7.0 Hz), 3.62 (2H, s), 1.26 (3H, t, J=7.0 Hz).
