实验步骤: The crude 2-chloro-4-{[p-(p-hexylphenyl)benzoyl]oxy}benzoyl chloride obtained was dissolved in 125 ml of benzene and then added dropwise to a solution of 4.0 g of 3-chloro-4-cyanophenol in 100 ml of pyridine. The mixture was stirred at a bath temperature of 65° C. overnight, then poured into ice-cold, dilute hydrochloric acid and extracted with diethyl ether. The extract was washed several times with 3N hydrochloric acid, then washed neutral with water, dried and evaporated. The crude 4'-hexyl-4-biphenylcarboxylic acid 3-chloro-4-[(3-chloro-4-cyanophenoxy)carbonyl]phenyl ester obtained was chromatographed on silica gel with toluene/dichloromethane (1:1). The fractions (8.2 g) which were practically pure according to thin-layer chromatography were recrystallized once from ethyl acetate and once from ethyl acetate and a small amount of hexane; m.p. (C-N) 95° C., cl.p. (N-I) 235° C. extracted with diethyl ether The extract was washed several times with 3N hydrochloric acid washed neutral with water dried evaporated
