実験手順

2-Chloro-3-cyanopyridine (2.77 g), hydrazine (5 mL), and dioxane (100 mL) were combined in a sealed tube and heated at 150° C. for 16 hr. The reaction mixture was cooled to room temperature and concentrated in vacuo to provide a crude residue. The resultant residue was dissolved in ethyl acetate (100 mL) and washed with saturated NaCl solution (50 mL). The organic layer was dried over sodium sulfate, filtered, and concentrated in vacuo to afford 1H-pyrazolo[3,4-b]pyridin-3-ylamine as a yellow solid which was used without further purification.
