Reaction Steps
6-(1-methyl-1H-pyrazol-4-yl)-1-(piperidin-3-ylmethyl)-1H-[1,2,3]triazolo[4,5-b]pyrazine (0.26 g, 0.89 mmol) was dissolved in EtOH (15 ml), and then 5-bromo-2-chloropyrimidine (0.33 g, 1.33 mmol) and DIPEA (0.77 ml, 4.43 mmol) were added, followed by stirring at 50° C. overnight. After the completion of the reaction, the reaction mixture was extracted with H2O, EA, and brine, followed by drying (Na2SO4), filtration, and concentration under reduced pressure, and the residue was purified by column chromatography (EA:Hex=1:1), to give (1-((1-(5-bromopyrimidin-2-yl)piperidin-3-yl)methyl)-6-(1-methyl-1H-pyrazol-4-yl)-1H-[1,2,3]triazolo[4,5-b]pyrazine (0.28 g, 70%).
