Procedure

A mixture of 6-chloro-N-(5-isopropoxy-1H-pyrazol-3-yl)-3-nitropyridin-2-amine (Intermediate 7, 0.4 g) and [(1S)-1-(5-fluoropyrimidin-2-yl)ethyl]amine hydrochloride (Intermediate 15, 0.25 g) in n-BuOH (5 mL) with diisopropylethylamine (1.5 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 0.55 g of desired product. MS (electrospray): 403 (M+1) for C17H19FN8O3. 1H NMR (300 MHz, CD3OD) δ ppm 8.40 (s, 2H) 8.10 (d, 1H) 6.15 (d, 1H) 5.60 (s, 1H) 5.35 (m, 1H), 4.60 (m, 1H) 1.50 (d, 3H) 1.20 (d, 6H).
