Reaction Steps

To a solution of 2-bromopyridine-3-carbaldehyde (2.04 g) in ethanol (25 mL) is added hydroxylamine hydrochloride (948 mg, 13.16 mmol) and sodium ethanoate (1.09 g, 13.16 mmol). The mixture is stirred at room temperature overnight. The solvent is evaporated under reduced pressure and the residue partitioned between dichloromethane and water. The organic layer is separated, dried over sodium sulfate, filtered and solvent evaporated in vacuo to give 2 g of 2-bromopyridine-3-carbaldehyde oxime. MS (m/z): 201/203 (M+1/M+3)
