Reaction Steps

Cesium carbonate (1.9 g) and 1H-1,2,3-triazole (540 mg) were added to a tube containing a DMF (2 ml) solution containing 2-chloropyridin-4-amine (500 mg) and the tube was sealed, followed by stirring at 180° C. for 6 hours. Water was added to the reaction solution, followed by extraction with ethyl acetate. The resultant was washed with saturated saline and dried over anhydrous sodium sulfate. Subsequently, the solvent was distilled away under reduced pressure. The obtained residue was purified by silica gel chromatography (n-hexane:ethyl acetate=1:3 to 0:1), and a white solid of 2-(2H-1,2,3-triazol-2-yl)pyridin-4-amine (75.7 mg) and brown oily matter of 2-(1H-1,2,3-triazol-1-yl)pyridin-4-amine (25.1 mg) was thus obtained.
