Procedure

A mixture of 17.8 g of 1-iodo-naphthalene, 4.4 g of paraformaldehyde, 10.4 ml of acetic acid, 14.6 ml of concentrated hydrochloric acid and 6.6 ml of phosphoric acid was stirred at 80° to 85° C. and thereto another 20 ml of concentrated hydrochloric acid was added with stirring 8 times at intervals of 1 hour. The reaction mixture was poured into water and was extracted with benzene. After distilling away benzene, 18.5 g of 4-iodo-1-chloromethylnaphthalene was obtained.
