Anisole (6.75 g, 62.4 mmol) was dissolved in dichloromethane (80 ml). The mixture was cooled to −5° C. and aluminum chloride (8.32 g, 62.4 mmol) was added. 4-Chlorobutyryl chloride (8.8 g, 62.4 mmol) was added dropwise to the mixture at −10° C. and stirred at −10° C. for 1 hour. The reaction mixture was poured into iced water (100 ml). After separation, the organic layer was washed with 1N hydrochloric acid (50 ml), saturated aqueous sodium hydrogen carbonate (50 ml) and water (50 ml), and was concentrated under reduced pressure to give 4-chloro-1-(4-methoxyphenyl)-1-butanone (12.7 g).
