Versuchsvorschrift

0.1 mol of dicyclohexylcarbodiimide (DCC) in 30 ml of CH2Cl2 is added with stirring at about 10° to a mixture of 0.1 mol of 4-(pentafluoroethyl)-phenol (preparation analogously to Bull. Chem. Soc. Japan, 57 (1984) 3361), 0.1 mol of trans-4-(trans-4-pentylcyclohexyl)cyclohexanecarboxylic acid and 0.01 mol of dimethylaminopyridine and 150 ml of CH2Cl2, and the mixture is then stirred for 15 hours at room temperature. It is filtered over silica gel, the solvent is evaporated and further purification gives 4-(pentafluoroethyl)-phenyl trans-4-(trans-4-pentylcyclohexyl)-cyclohexanoate.
