Optically active 1,1,1-trifluoro-2-octanol (0.3 g), dimethylformamide (0.2 g) and triethylamine (0.18 g) were dissolved in methylene chloride (20 ml). To this solution was added in small portions a solution of 2,6-naphthalenedicarboxylic acid dichloride (0.8 g) obtained in the step 2) of Example 7 in methylene chloride (50 ml) under ice-cooling, and the mixture was stirred for about 20 hours. Next, 4-n-octyloxycarbonyl-4'-hydroxybiphenyl (0.55 g) obtained in the step 1) was dissolved in methylene chloride (30 ml) and added in small portions to the reaction mixture.
