Reaction Steps

To a solution of 1-acetyl-4-(6-{2-[4-(chloromethyl)phenyl]ethyl}pyridin-3-yl)piperazine (234.8 mg, 0.656 mmol) in anhydrous N,N-dimethylformamide (5 ml) was added sodium azide (426.5 mg, 6.561 mmol), and the mixture was stirred at room temperature for 16 hrs. Aqueous sodium carbonate solution and ethyl acetate were added to the reaction mixture. The mixture was stirred, stood still and partitioned. The organic layer was dried over anhydrous magnesium sulfate, and concentrated to dryness to give 1-acetyl-4-(6-{2-[4-(azidomethyl)phenyl]ethyl}pyridin-3-yl)piperazine (226.8 mg, yield 94.9%) as a slightly yellow solid.
