Procedure

A vigorously stirred mixture of hydroxylamine hydrochloride (924 mg, 13.3 mmol), water (4 mL), NaHCO3 (1.12 g, 13.3 mmol), 3-bromo-2-cyanomethylpyridine (Intermediate 1) (1.31 g, 6.65 mmol) and ethanol (14 mL) was heated to reflux for 5 h. The reaction mixture was allowed to cool to room temperature, the ethanol was removed in vacuo and the white solid collected by filtration, washing with water (3×10 mL). The wet solid was dried in vacuo at 40° C. for 1 hour to yield 2-(3-Bromo-pyridin-2-yl)-N-hydroxy-acetamidine as a solid (Intermediate 2).
