실험 절차

Hydrazine (3.86 ml, 79 mmol) is added at room temperature to 7 g (26.5 mmol) of a solution of 2-chloro-5-iodonicotinonitrile in 25 ml of propan-2-ol. The reaction mixture is heated at 85° C. for 7 hours and then at room temperature overnight. The suspended solid is filtered, rinsed with isopropanol and then with ether and dried in an oven at 50° C. to give 6 g (87%) of 5-iodo-1H-pyrazolo[3,4-b]pyridine-3-amine.
