Procedure

Combine 4-hydroxybenzophenone (8 kg, 57.6 mol), potassium carbonate (8 kg, 57.6 mol), and 1-bromo-4-chlorobutane (8.384 kg, 48.9 mol) in acetone (40 L). Heat to reflux. After 20 hours, cool the reaction mixture and filter. Rinse the filter cake with acetone and evaporate the filtrate in vacuo to obtain 4-(4-chlorobutoxy) benzophenone.
