Procedure
211 mg (1.18 mM) of decyloxybiphenylcarboxylic acid and 2.5 ml of thionyl chloride were heat-refluxed for 2 hours, followed by distilling-off of excessive thionyl chloride. To the resultant acid chloride was added a solution of 339 mg (1.18 mM) of 2-cyano-2-methylhexyl p-hydroxybenzoate and 263 mg (2.36 mM) of thiethylenediamine in 5 ml of dry benzene, followed by 2 hours of stirring under heating at 50° C. Then, a solution of 56.5 mg (2.36 mM) of sodium hydride in 2 ml of dry benzene was added, followed by 2 hours of heat-refluxing. After the reaction, the mixture was cooled to room temperature, followed by addition of 5 ml of 1N-hydrochloric acid and 12 ml of distilled water and extraction with ether. The ether solution was dried on sodium sulfate, followed by distilling-off of the solvent and purification by thin layer chromatography (developer solvent: benzene/methylene chloride=1:3) to obtain 230 mg of 2-cyano-2 -methylhexyl p-(p-decyloxybiphenyl carbonyloxy)benzoate. Yield: 32.1%. [α]D -4.6 degrees (c1, methylene chloride). Phase transition temperatures (°C.): ##STR34##
