A suspension of 1H-pyrazole (0.42 g, 0.0061 mol), 5-bromopyrimidin-2-amine (1.3 g, 7.3 mmol), copper(I) iodide (58.2 mg, 0.306 mmol), N,N′-dimethylcyclohexane-1,2-diamine (0.193 mL, 1.22 mmol), potassium carbonate (1.77 g, 12.8 mmol) in N,N-dimethylformamide (5.00 mL) was irradiated under microwave at 180° C. for 1 h. After cooling, the mixture was purified by chromatography on silica gel with methanol in methylene chloride (0-10%) to afford the desired product. LCMS: (M+H)=162.1.
