4-Carbobenzoxyoxybenzoic acid 1-methylpropyl ester → 2-Butyl p-hydroxybenzoate

Participants

Reaction Steps

A solution of 10 m moles (3.1 g) of the above 4-carbobenzoxyoxybenzoic acid 1-methylpropyl ester and 0.5 g of palladium carbon (5% catalyst) in 40 ml of ethyl acetate was reacted for four hours in an atmosphere of hydrogen gas. After the reaction, palladium carbon was filtered out using a membrane filter, and the filtrate was concentrated, then purified by column chromatography to obtain 1.7 g of 4-hydroxybenzoic acid 1-methylpropyl ester. (yield: 86%)
