Reaction Steps
N-(2-chloropyrimidin-4-yl)-2,3-dimethyl-2H-indazol-6-amine (2.21 g; 8 mmol, 1 equiv) was dissolved in DMF (11 ml) and cesium carbonate (7.9 g; 24.2 mmol, 3 equiv) was added. The reaction mixture was stirred for 30 min under nitrogen. Iodomethane (0.8 ml, 13 mmol, 1.6 equiv) was added and the reaction mixture was stirred at room temperature for 2 hrs. The reaction mixture was poured in ice cold water and stirred for 30 minutes. The resulting precipitate was collected by filtration to yield the desired compound (0.84 g, 37%).
