Participants

Reaction Steps

8.00 g (71.29 mmol) of potassium tert-butoxide and 5.20 g (69.27 mmol) of acetohydroxamic acid are dissolved in 50 ml of dry dimethylformamide and stirred at room temperature for 1 hour. After the addition of 4.40 g (23.51 mmol) of 2-(difluoromethoxy)-6-fluorobenzonitrile, the mixture is stirred first at room temperature for 3 hours and then at 60° C. for 16 hours. The mixture is concentrated under reduced pressure, the residue is stirred with water and the pale olive-coloured precipitate is filtered off with suction. This gives 4.4 g of product, which, according to LC-MS, is about 89% pure.
