Versuchsvorschrift

Hydroxylamine (1.00 mL of a 50% aqueous solution, 16.3 mmol) was added to a solution of 3-bromobenzonitrile (750 mg, 4.12 mmol) and potassium carbonate (1.00 mg, 7.24 μmol) in EtOH (3.00 mL). The resulting mixture was heated to 120° C. in a sealed microwave vial for 40 min. After cooling to rt, the reaction mixture was concentrated in vacuo to afford the title compound i-3a. m/z (ES) 215 (MH)+.
