Participants

Reaction Steps

A solution of 3-cyanophenylacetic acid (0.2 g, 1.24 mmol) in a mixture of trifluoroacetic acid (1 ml) and concentrated sulfuric acid (0.5 ml) was stirred at room temperature for 16 h. The reaction mixture was then poured into ice-cold water and the resulting solid was filtered, washed with water and dried under vacuum to give 2-[3-(aminocarbonyl)phenyl]acetic acid (0.167 g, 75% yield). MS (EI) for C9H9NO3: 178 (M−H).
