HCID 4049156Ethyl 4'-hydroxy-4-biphenylcarboxylate収率 97%

実験手順

1 ml of conc. sulfuric acid was added to an ethanol solution of 0.1 mole(21.4 g) of 4'-hydroxybiphenyl-4-carboxylic acid, and stirred for 18 hours. The reaction solution was concentrated, and then purified by column chromatography, to obtain 22.8 g of 4'-hydroxybiphenyl-4-carboxylic acid ethyl ester [m.p. 144.4°-145.6° C⟧ (yield: 97%)
