4-羟基苯甲酸仲丁酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 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%) was filtered out filter the filtrate was concentrated purified by column chromatography
