Reaction Steps

0.29 g (0.91 mmol) of 3-fluoro-5-hydroxy-2-(4-octyloxyphenyl)pyridine, 0.19 g (0.91 mmol) of dicyclohexylcarbodiimide, 0.16 g (0.91 mmol) of trans-4-pentylcyclohexanecarboxylic acid and 0.01 g of 4-(N,N-dimethylamino)pyridine are stirred at room temperature for 18 hours in 10 ml of dichloromethane. Filtration, evaporation to dryness, chromatographic purification (silica gel/hexane: ethyl acetate 8:2) and recrystallization from acetonitrile give 0.19 g of 3-fluoro-2-(4-octyloxyphenyl)pyridin-5-yl trans-4-pentylcyclohexanecarboxylate. ##STR28## The compound has the phase sequence: X 65.2 (40.2) Sc 63 SA 129 N 173 I.
