Nitric Acid → 2-(4-Methyl-3-nitrophenyl)acetic acid

Participants

Reaction Steps

To a solution of 4-methylphenylacetic acid (1.50 g, 10.0 mmol) in dried dichloromethane was added nitric acid (fuming, 1.5 mL) dropwise. The mixture was stirred at room temperature for 2 hours, then quenched with water and extracted with ethyl acetate. The extracts were washed with water twice and brine, dried over magnesium sulfate, filtered, and concentrated to provide the title compound (1.66 g, 85% yield): 1H NMR (CDCl3) 7.91 (d, 1H), 7.42 (dd, 1H), 7.31 (d, 1H), 3.71 (s, 2H), 2.58 (s, 3H); ES-MS m/z 196 [M+H]+.
