Procedure

A mixture of 42.86 g of 4-chloro-1-naphthol, 27.6 g of p-fluoroacetophenone, 33.12 g of potassium carbonate and 200 ml of dimethylacetamide was heated at 150° C., under argon for 18 hours, then poured into ice water, stirred and extracted with ethyl acetate. The extract was washed with 0.5N sodium hydroxide, 0.5N hydrochloric acid, water and brine, dried and evaporated to a residue. This residue was boiled in hexane, then cooled and the intermediate collected to yield the product as white crystals, mp 95°-99° C.
