A mixture of 2-chloro-N-(5-cyclopropyl-1H-pyrazol-3-yl)-5-nitropyrimidin-4-amine (Intermediate 17, 0.35 g) and [(1S)-1-(5-fluoropyridin-2-yl)ethyl]amine hydrochloride (Intermediate 5, 0.25 g) in n-BuOH (10 mL) with diisopropylethylamine (1 mL) was stirred at 70° C. for 4 hours. The resulting mixture was diluted with ethyl acetate (20 mL), and washed with brine (10 mL×3). The organic layer was dried and concentrated. The resulting residue was separated by silica gel column (Hexane/Ethyl acetate) to yield 0.3 g of desired product. MS (electrospray): 385 (M+1) for C17H16FN8O2.
