Reaktionsschritte
6M Sodium hydroxide (25 mL) was added to 3-acetylbenzonitrile (850 mg, 5.82 mmol) in methanol (25 mL) and then heated at 90° C. overnight. After concentrating the reaction mixture, the aqueous layer was washed with dichloromethane (2×), then acidified pH˜3 with 12M HCl. The precipitate was extracted with ethyl acetate then washed with water and saturated brine, dried over anhydrous sodium sulfate filtered and concentrated to afford 3-ethylbenzoic acid as a colorless oil; 0.800 g (92%). 1H NMR (CDCl3) δ (ppm): 8.70 (s, 2H), 8.33 (d, 2H), 8.24 (d, 2H), 7.64 (t, 1H), 2.70 (s, 3H).
