Procedure: A slurry of 3.0 g of 3-dimethylaminophenol, 6.05 g of milled potassium carbonate and 75 ml of acetone was stirred at room temperature under nitrogen for 30 minutes and then a solution of 7.66 g of α-bromo-3-chloroacetophenone in 75 ml of acetone was added dropwise. The slurry was stirred at room temperature for 72 hours. Filtration and evaporation gave a residue which was purified by high performance liquid chromatography (7:1 hexane-ethyl acetate). The resulting solid was recrystallized from ethyl acetate-hexane to give 3.0 g of 1-(3-chlorophenyl)-2-[3-(dimethylamino)phenoxy]ethanone, m.p. 101°-103° C. Filtration and evaporation gave a residue which was purified by high performance liquid chromatography (7:1 hexane-ethyl acetate) The resulting solid was recrystallized from ethyl acetate-hexane
