Hydroxyphenylacetic acid → 4-Hydroxy-3-nitrophenylacetic acid

Participants

Reaction Steps

4-Hydroxyphenylacetic acid (50 g, 0.32 m) in 300 ml of glacial acetic acid was cooled to 10°, at which temperature 100 ml of nitric acid was slowly added. The mixture was allowed to reach room temperature, then was poured into 1 of water. The separated solid was washed with water and recrystallized from ethanol to give 35 g of 4-hydroxy-3-nitrophenylacetic acid, m.p. 144°-146°.
