Reaction Steps
p-n-Octylbenzoic acid chloride prepared from 7 g of p-n-octylbenzoic acid and excess thionyl chloride was dissolved in toluene, and the solution was admixed with a pyridine solution of 8.3 g of said 4-hydroxy-4'-biphenylcarboxylic acid 2-methylbutyl ester for reaction at 80° C. for 3 hours. The crude product was obtained in the same manner as described in Example 1 and recrystallized twice from ethyl acetate to obtain p-n-octylbenzoic acid 4'-(2-methylbutoxycarbonyl)-4-biphenylyl ester.
