Reaction Steps
Dimethylaminopyridine 0.01 g and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride 0.8 g were added to a methylene chloride (50 ml) solution of 4-(4-allyloxybutyloxy)benzoic acid 0.84 g and 2-(4-octyloxybenzoyloxy)-7-hydroxy-9-methylfluorene (J1) 1.5 g while maintaining 5° C., and the mixture was further stirred at room temperature for 12 hours. Water 50 ml was added thereto, and the resulting organic layer was dried on anhydrous magnesium sulfate. A residue obtained by distilling the solvent off was refined by silica gel column chromatography to obtain 0.5 g of 2-[4-(4-allyloxybutyloxy)benzoyloxy]-7-(4-octyloxybenzoyloxy)-9-methylfluorene (J2).
