Reaction Conditions

Reaction Steps

A solution of the 4-bromo-2-chloro-6-methyl-benzoic acid methyl ester (1.31 g, 5 mmol) in DMF was treated with CuCl (1.96 g, 20 mmol) and stirred at 140° C. for 1-2 h. After this time, the reaction mixture was diluted with dichloromethane (15 mL) and the solids removed by filtration. The filtrate was concentrated. Silica gel column chromatography using, typically 30% ethyl acetate in hexane, afforded 2,4-dichloro-6-methyl-benzoic acid methyl ester (0.72 g, 65%).
