Procedure

To a mixture of 3-(4-(benzyloxy)-3,5-difluorophenyl)-2-methylpropanoate (752) (1.09 g, 3.26 mmol) in tetrahydrofuran (10 mL), water (10 mL), and methanol (20 mL) was added lithium hydroxide (547 mg, 13.04 mmol) and the solution was stirred overnight at 80° C. The reaction was concentrated, acidified with 1N hydrochloric acid, and extracted with ethyl acetate. The organic layer was dried over sodium sulfate, filtered, and concentrated in vacuo to yield 3-(4-(benzyloxy)-3,5-difluorophenyl)-2-methylpropanoic acid (753).
