Reaction Steps
A 5000 mL three-neck flask was charged with 4-hydroxybenzophenone (800.0 g; 4.036 mol), 1-bromo-3-chloropropane (832.5 g; 5.288 mol) and 2-butanone (3300 mL). Anhydrous potassium carbonate (673.6 g; 4.874 mol) was added and the reaction mixture was stirred at reflux for 100 h. Full consumption of the starting 4-hydroxybenzophenone was confirmed by HPLC. The reaction mixture was filtered, the inorganic solids were washed with 2-butanone (3×100 mL). The filtrate was evaporated, and the unreacted 1-bromo-3-chloropropane was removed by heating to 70° C. in vacuo. The residue was dissolved in acetonitrile (2000 mL) and sodium iodide (650.0 g; 4.337 mol) was added. The reaction mixture was refluxed for 8 h. The reaction mixture was filtered to give a solution of crude 4-(3-iodopropoxy) benzophenone.
