실험 절차
To a 0° C. solution of 6-methylpyridin-3-amine (12 g, 0.11 mol) in cone HCl (40 mL) was added a solution of NaNO2 (7.7 g, 110 mmol) in water (30 mL) and the resulting mixture was stirred at 0° C. for 1 h. A solution of SnCl2 (50 g, 0.22 mol) in cone HCl (60 mL) was added at 0° C. The reaction solution was warmed to RT and stirred for 2 hours. The precipitate was collected by filtration to provide 5-hydrazinyl-2-methylpyridine hydrochloride (10 g, 57% yield) which was used without further purification.
