52 g of 2,7-dibromo-9-(2,5-dimethylphenyl)-9-(4-hydroxyphenyl)fluorene were refluxed with 18 g of 3,7-dimethyloctyl chloride, 80 ml of ethanol, 7 g of KOH and 1 g of NaI for 5 days. According to TLC, the reaction was complete after this time. The solvent was stripped off, ethyl acetate was added, and the precipitate was filtered off with suction and rinsed a number of times with ethyl acetate.
