PROCEDURE

实验过程

60 m moles(10.9 g) of tetramethylammonium hydroxide pentahydrate was added into a DMF solution of 60 m moles(3.6 g) of acetic acid, stirred for one hour, then 50 m moles(27.3 g) of the above 4'-(16-bromohexadecyloxy)biphenyl-4-carboxylic acid ethyl ester was added, and stirred for 12 hours. The reaction solution was ether extracted and concentrated, then purified by column chromatography to obtain 18.1 g of 4'-(16-acetyloxyhexadecyloxy)biphenyl-4-carboxylic acid ethyl ester. (yield: 69%)
