A mixture of 2,4-dichloro-5-nitropyrimidine (2 g) and 5-isopropoxy-1H-pyrazol-3-amine (Intermediate 6, 1.5 g) in acetonitrile (50 mL) with triethylamine (5 mL) was stirred at room temperature for 24 hours, The resulting mixture was concentrated, and the resulting residue was separated by silica gel column (Hexane/Ethyl acetate) to afford 1 g of the title compound. MS (electrospray): 299 (M+1) for C10H12ClN6O3.
