反応手順
60 m moles(10.9 g) of tetramethylammonium hydroxide pentahydrate was added to a DMF solution of 60 m moles(3.6 g) of acetic acid, and stirred for one hour, then 50 m moles(24.5 g) of the above 4'-(12-bromododecyloxy)biphenyl-4-carboxylic acid ethyl ester was added thereto, and stirred for 12 hours. After the reaction, the reaction solution was ether extracted. The extrate was concentrated, and then purified by column chromatography, to obtain 15.7 g of 4'-(12-acetyloxydodecyloxy)biphenyl-4-carboxylic acid ethyl ester [m.p. 80.1°-81.5° C⟧ (yield: 67%)
