Reaction Steps

A solution of 2-fluoro-4-hydroxyaniline (7.1 g) and potassium hydroxide (3.7 g, 85% pure) in dimethylsulphoxide (25 ml) was heated to 80° C. and treated with a solution of 1,2-dichloro-4-(trifluoromethyl)benzene (10.9 g) in dimethylsulphoxide (10 ml). The mixture was stirred at 90°-95° C. for 20 hours, after which time it was diluted with a mixture of water and dichloromethane. The organic phase was dried over sodium sulphate and evaporated down to give 3.6 g of the crude desired product as a brown oil.
