Procedure
To 3,5-difluorobenzophenone (2.5 g) in ethanol (30 mL) was added hydroxylamine hydrochloride (3 eq) and sodiumcarbonate (3 eq). The reaction mixture was stirred at reflux for 4 hours and then allowed to cool down to room temperature. The precipitate was then isolated by filtration and washed with water to yield the title compound as a white solid (m.p.=91-93° C., Yield=89%), reflux, 4 h
