Versuchsvorschrift
A mixture of methyl 4-carboxycinnamate (1.5 g) and 10% palladium on carbon (300 mg) in methanol (5 ml) was stirred for 2 hours at ambient temperature under hydrogen atmosphere. Insoluble material was filtered off, and the filtrate was concentrated in vacuo to give 4-[2-(methoxycarbonyl)ethyl]benzoic acid (1.3 g).
