Reaction Steps
An acetone solution of 90 m moles (21.8 g) of the above 4'-hydroxybiphenyl-4-carboxylic acid ethyl ester, 0.15 mole (49.2 g) of 1,12-dibromododecane, 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 29.5 g of 4'-(12-bromododecyloxy)biphenyl-4-carboxylic acid ethyl ester [m.p. 88.6°-90.5° C⟧ (yield: 67%)
