A solution of p-(2-(butoxycarbonyloxy)-propoxy)-phenol (1 g) prepared in Example 4 in tetrahydrofuran (20 ml) was dropwise added to a suspension of sodium hydride (0.2 g) in tetrahydrofuran, followed by dropwise adding to the mixture, a solution of 4'-octyl-4-chloromethylbiphenyl (1.2 g) in dimethylformamide (50 ml), agitating the mixture at 60° C. for 10 hours, pouring the reaction solution in water, extracting the resulting material with toluene (300 ml), washing the extract with an acid, then with an alkali and further with water, purifying it according to column chromatography using a column having activated alumina filled therein and recrystallizing from a mixed solvent of ethyl acetate with ethanol to obtain the objective 4'-octyl-4-(4-(2-(butoxycarbonyloxy)-propoxy)-phenoxymethyl)-biphenyl (0.5 g) having a m.p. of 94° C.
