Versuchsvorschrift

Optically active 1,1,1-trifluoro-2-octanol (0.5 g), dimethylformamide (0.35 g) and triethylamine (0.64 g) were dissolved in 20 ml of methylene chloride. To this solution was added in small portions a solution of 4,4'-biphenyldicarboxylic acid dichloride (1.6 g) obtained in 2) of Example 7 in 50 ml of methylene chloride under ice-cooling, and the mixture was stirred for about 20 hours. Next, 2-hydroxy-6-octyloxycarbonylnaphthalene (0.86 g) obtained in 1) was dissolved in 30 ml of methylene chloride and added in small portions to the reaction mixture. The resulting mixture was stirred for about 20 hours.
