60 °C

A solution of 1.6 mL (15 mmol) of 4-chloro-2-fluorophenol and 1.68 g (15 mmol) of potassium tert. butoxide in 10 mL DMSO was stirred for one hour at ambient temperature. Then 2.1 g (15 mmol) of 3,4-difluoro-benzonitrile were added and the mixture was stirred overnight at 60° C. The mixture was then combined with approx. 50 mL water, then extracted three times with 30 ml of ethyl acetate. The organic extracts were washed with sodium chloride solution, dried on sodium sulphate and evaporated down. The product thus obtained was reacted further without any further purification.
