実験手順

Sodium acetate (166 mg, 2.02 mmol), thiosemicarbazide (333 mg, 3.66 mmol), 100 ml ethanol and 2 ml distilled water were charged into a 250 ml round bottom flask. The resulting suspension was heated to 80° C. until it becomes a clear solution. The reaction was then cooled down to room temperature and the resulting mixture was added into a 250 ml round bottom flask containing 3-methyl-1H-pyrazolo[3,4-b]pyridine-5-carbaldehyde (333 mg, 2.1 mmol). After the addition, the resulting mixture was heated to 80° C. for 16 hours. The mixture was cooled to room temperature and solid was precipitated out. The solid was filtered off and washed with ether (50 ml). The product (500 mg, y=95%) was used directly for the next step without further purification.
