At room temperature, 3 ml of N,N-dimethylformamide (DMF) was placed in a flask, and 0.27 g of NaH (60% in oil) was added thereto. Then, 0.3 g (0.925 mmol) of 2,3,6,7,10,11-hexahydroxytriphenylene was added thereto, and after 1 hour of stirring, a mixture liquid of 1.96 g (6.84 mmol) of 4-methylhexyl p-toluenesulfonate and 2 ml of DMF was added dropwise thereto, followed by 5 hours of stirring at 70° C. After the reaction, the system was cooled to room temperature, and water was added thereto to precipitate a crystal, which was recovered by filtration. The crystal was then purified by silica gel chromatography (with toluene) and re-cystallized from acetone/methanol to obtain 0.24 g of 2,3,6,7,10,11-hexa(4-methylhexyloxy)triphenylene.
