Reaction Steps
2 g of 2,6-dichloropyridine were dissolved in 60 ml of methanol and mixed with 10 ml of 80% hydrazine hydrate. The solution was firstly stirred for 3 days at room temperature and then refluxed for 10 days. Rotation in took place, the residue was taken up with methanol, followed by rotation in again and finally recrystallization from methanol/water. 0.25 g of 2-hydrazino-6-chloropyridine was obtained.
