Reaction Steps

25 mmol of 4,4"-terphenyldicarboxylic acid (obtainable by reaction of dibromoterphenyl with CuCN in NMP and hydrolysis of the dinitrile with KOH in diethylene glycol), 7.9 g of (S)-3,7-dimethyloctanol and 0.12 g of DMAP are taken in 40 ml of toluene. A solution of 9.9 g of DCC in 15 ml of toluene is added dropwise at room temperature, with stirring, the mixture is stirred overnight and chromatographed with toluene on silica gel and the product is recrystallized to give 4,4"-bis-(3,7-dimethyloctyloxycarbonyl)-p-terphenyl.
