Reaction Steps

1,2,3-Triazole (45 mg), cesium carbonate (260 mg), trans-N,N′-dimethylcyclohexan-1,2-diamine (76 mg), and copper iodide (50 mg) were added to a DMAc (2 ml) solution containing 5-bromo-6-methylpyridin-3-amine (100 mg) in a nitrogen atmosphere, followed by stirring in a sealed tube at 110° C. for 8 hours. The reaction solution was adjusted to room temperature and water was added to the reaction solution, followed by extraction with ethyl acetate and washing with saturated saline. The organic layers were dried over anhydrous sodium sulfate. Next, the solvent was distilled away under reduced pressure and the obtained residue was purified by silica gel chromatography (chloroform:MeOH=1:0 to 20:1). A white solid of 6-methyl-5-(2H-1,2,3-triazol-2-yl)pyridin-3-amine (12.8 mg) and brown oily matter of 6-methyl-5-(1H-1,2,3-triazol-1-yl)pyridin-3-amine (6.7 mg) were thus obtained.
