Reaction Steps

A stirred mixture of 13.04 g (0.08 mole) of 2,4-dichlorophenol, 15.61 g (0.08 mole) 1-bromo-3-methoxy-3-methyl-2-butanone, and 11.1 g (0.08 mole) powdered potassium carbonate in 300 ml acetonitrile was heated at reflux temperature for 30 minutes. The reaction mixture was cooled, filtered, and the solvent evaporated from the filtrate. The residual oil was taken up in hexane and cooled to -20° C., whereupon the product separated as a white crystalline solid. There was thus obtained 19 g (85.7% yield) of 1-(2,4-dichlorophenoxy)-3-methoxy-3-methyl-2-butanone, m.p. 45.5°-47.5° C.
