Nitric Acid → 2-(3-Nitro-4-hydroxyphenyl)propionic acid

Participants

Reaction Steps

In a mixture of 8ml of nitric acid and 15ml of acetic acid 1g of 2-(4-hydroxyphenyl)propionic acid was added and stirred at -10° to -20° C for 4 hours. The reaction mixture was poured into ice water and extracted with chloroform. The extract was washed with a sodium hydrogen carbonate solution and water and then dried over magnesium sulfate. The chloroform solution was concentrated to give crystals, which were recrystallized from water. Yield, 700 mg (58%).
