Procedure
0.377 ml (2.63 mmol) of 35% hydrazine is added to 0.217 g (0.658 mmol) of 6-chloro-5-cyano-N-(3,5-difluorophenyl)pyridine-3-sulfonamide diluted in 6 ml of isopropanol. The solution is heated at 75° C. for 2 hours. The solvent is evaporated to yield 0.214 g of 3-amino-N-(3,5-difluorophenyl)-1H-pyrazolo[3,4-b]pyridine-5-sulfonamide in the form of a yellow solid (yield=100%).
