Reaction Steps
To a solution of lithium hydroxide (3.5 g, 0.042 mmol) in tetrahydrofuran, menthol and water (120 mL, 3:1:1) was added methyl 2-(4-bromophenyl)-2-phenoxyacetate (6.8 g, 0.021 mol). The reaction mixture was stirred at room temperature for 1 hour. The mixture was quench with 10% hydrochloric acid (aqueous, 5 mL), extracted with dichloromethane and menthol (10:1), the combine organic layer was dried with anhydrous sodium sulfate, filtered and evaporated to give 2-(4-bromophenyl)-2-phenoxyacetic acid (6 g, 80%). 1H NMR (300 MHz, DMSO-d6): δ 7.68-7.65 (m, 5H), 7.52-7.49 (m, 2H), 6.88-6.86 (m, 2H), 5.35-5.31 (m, 1H).
