Reaktionsschritte
An acetone solution of 90 m moles (21.8 g) of 4'-hydroxybiphenyl-4-carboxylic acid ethyl ester obtained in Example 24, 0.15 mole (57.6 g) of 1,16-dibromohexadecane, and 0.4 mole (55.3 g) of potassium carbonate was refluxed for four hours. The reaction solution was filtered. The filtrate was concentrated, and then purified by column chromatography to obtain 34.4 g of 4'-(16-bromohexadecyloxy)biphenyl-4-carboxylic acid ethyl ester. (yield: 70%)
