Reaction Steps

To 4,4′-dihydroxy-benzophenone (8.2 g, 38.3 mmol) and 1-bromodocosane (31.3 g, 80.4 mmol) were added DMF (300 mL) and potassium carbonate (15.9 g, 115 mmol), and the mixture was stirred at 80° C. for 6.5 hours. After confirmation of disappearance of monoalkylated form, the reaction mixture was ice-cooled and 1N hydrochloric acid (300 mL) and water (150 mL) were slowly added with sufficient stirring. The slurry was filtered, and the obtained crystals were washed with water and methanol to give 4,4′-didocosoxy-benzophenone (28.3 g, 34.1 mmol, 89%).
