Reaction Steps

1.0 g (7.2 mmol) of 3,4-difluorobenzonitrile was initially charged in 30 ml of ethanol, and a solution of 0.5 g (7.2 mmol) of hydroxylammonium chloride and 0.6 g (7.2 mmol) of sodium bicarbonate in 11 ml of water was added at RT. The reaction mixture was stirred at RT for 16 h, concentrated under reduced pressure and reacted without further purification.
