2-Docosyloxy-9-(4-chlorophenyl)-9-fluorenol (200 mg, 0.33 mmol) prepared in the above-mentioned 1-2 was dissolved in chloroform (2 ml), acetyl bromide (48 μl, 0.65 mmol) was added dropwise and the mixture was stirred for 1 hour. After completion of the reaction, the solvent was evaporated, and the residue was precipitated with acetonitrile (2 ml) to give 2-docosyloxy-9-(4-chlorophenyl)-9-bromofluorene (209 mg, 0.31 mmol, 95%).
