Reaction Steps

A mixture of methyl 2-chloro-4-(1-phenoxyethyl)benzoate (750 mg, 2.7 mmol), lithium hydroxide monohydrate (571 mg, 13.6 mmol), water (5 mL) and methanol (5 mL) in tetrahydrofuran (15 mL) was stirred at 20° C. for 5 hours. The reaction mixture was concentrated. The residue was acidified to pH=2 with concentrated hydrochloride solution. The mixture was extracted with ethyl acetate (20 mL×2). The organic phase was dried over sodium sulfate and filtered. The filtrate was concentrated. The residue was purified by column chromatography (silica gel, petroleum ether/ethyl acetate=2:1) to give 2-chloro-4-(1-phenoxyethyl)benzoic acid as a white solid (500 mg, 71%). LRMS (M+H+) m/z: 276.06. found 276.
