Reaktionsschritte

Pentafluorophenol (11.5 mmol) is added at 0° C. to a mixture of 10.5 mmol 4'-n-octyloxy-[1,1'-biphenyl]-4-ylcarboxylic acid and 10.5 mmol of dicyclohexylcarbodiimide in ethyl acetate. The mixture is stirred at 25° C. for a period of 18 hours whereupon a precipitate is formed. The reaction mixture is filtered, the filtrate washed with water and brine and dried, the solvent removed in vacuo to obtain pentafluorophenyl 4'-n-octyloxy[1,1'-biphenyl]-4-ylcarboxylate, C27H25F5O3, M.W. 492.5.
