Procedure

181 mg (1.5 mmol) pivaloyl chloride was added to a solution of 673 mg (1 mmol) 2-hydroxy-3,6,7,10,11-pentapentyloxytriphenylene (see Henderson et al., Liquid Crystals 18 (1995) 191) in 1 mL pyridine. The mixture was heated for one hour at 80° C., diluted with diethyl ether and extracted repeatedly with dilute HCl and sodium carbonate solution. Purification was performed by crystallization from ethanol.
