In a 100 ml double-necked flask, <strong>[4877-80-9]2,3,6,7,10,11-hexahydroxytriphenylene</strong> (50 mg, 0.15 mmol) was dissolved in dry DMF (5 ml) in a nitrogen stream. To the solution were added finely ground potassium carbonate (0.13 g, 6.0 eq.) and dodecyl bromide (246.7 mg, 6.6 eq.) and the resultant mixture was stirred overnight at 60° C. There was added 200 ml of distilled water and the precipitate was collected by filtration and washed with methanol. The crude product was dissolved in chloroform and purified by column chromatography (silica gel; hexane: chloroform=2:1) to give compound 3 as white solid (70 mg/35percent). The product was identified by MALDI-TOF-MS, elemental analysis and 1H-NMR (see Table 2). MALDI-TOF-MS (CHCA): m/z 1334.82 (Calcd for [M+H]+1334.50); Anal. Calcd for C90H156O6.0.75CHCl3: C, 76.56; H, 11.10percent. Found: C, 76.45; H, 11.52percent.
