Procedure

Hydroxylamine (Fluka 55458; 50% in water; 4.81 mL; 80.16 mmol; 5 eq.) was added to a solution of 2-(trifluoromethoxy)benzonitrile (Apollo PC7438E; 3 g; 16.03 mmol; 1 eq.) in EtOH (20 mL) and the reaction mixture was stirred at 60° C. for 10 hours. Evaporation in vacuo gave a white solid, which was further dried under high vacuum to afford the title compound (3.30 g, 94%) as a white solid.
