Reaktionsschritte

4-Chlorobutyrophenone (15.18 g, 0.083 moles), ethanediol (6.80 g, 0.110 moles) and p-toluene sulphonic acid (0.20 g) were heated in toluene at reflux and water was removed from the reaction using a Dean and Stark apparatus. After 17 hours the solvent was removed by distillation in vacuo to leave crude 2-phenyl-2-(3-chloropropyl)-1,3-dioxolane (21 g).
