Reaction Steps

0.36 g of 4-(4'-n-octyloxyphenyl)benzoic acid, 0.21 g of (S,S)-4-(3'-chloro-1'-methylbutoxy)phenol, 0.02 g of 4-pyrrolidinopyridine, 0.21 g of dicyclohexylcarbodiimide and 10 ml of methylene chloride were stirred together at room temperature for four hours. The dicyclohexyl urea thus precipitated was filtered and the filtrate was desolvated. The obtained residue was purified by silica gel column chromatography with the use of a mixture of n-hexane and ethyl acetate (9:1) as a developing solvent to thereby give the title compound.
