2-(2-Carboxyethenyl)benzoic acid → 3-(2-Carboxyphenyl)propionic acid

Participants

Reaction Steps

A mixture of 2-(2-carboxyvinyl)benzoic acid (5 g, 26 mmol) in MeOH (45 mL) was bubbled with H2 (10 psi) at room temperature overnight. The mixture was filtered and the filtrate was concentrated to give 2-(2-carboxyethyl)benzoic acid (5.2 g, 100%). 1H-NMR (CDCl3): 2.61 (m, 2H), 3.21 (m, 2H), 7.22 (m, 2H), 7.38 (m, 1H), 7.88 (m, 1H).
