To a solution of 4-benzyloxybiphenyl-4'-carboxylic acid chloride (1.23 g) in methylene chloride (10 ml) was added by little and little under ice-cooling a solution of (R)-(+)-1,1,1-trifluoro-2-octanol (0.96 g) ([α]D22.5 =+20.1, optical purity 96.3%ee), dimethyl-aminopyridine (0.55 g) and triethylamine (0.48 g) in methylene chloride (20 ml). The mixture was left to stand over-night at room temperature in order to complete the reaction before the mixture obtained was poured in ice-water.
