To a solution of methyl 3-(2-cyanoethyl)benzoate (169 mg, 893 μmol) in methanol (3 mL)/tetrahydrofuran (1 mL) was added 2N aqueous sodium hydroxide solution (893 μL, 1.79 mmol), and the mixture was stirred at 60° C. for 4 hr. The reaction mixture was neutralized with 6N hydrochloric acid (500 μL), 1N hydrochloric acid (15 mL) was added, and the mixture was extracted with ethyl acetate (20 mL, 5 mL). The combined organic layer was washed with saturated brine (5 mL), and dried over anhydrous magnesium sulfate. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure to give the title compound (151 mg, 96%) as a white solid.
