Reaction Steps

A mixture of 2-chloro-N-(5-isopropoxy-1H-pyrazol-3-yl)-5-nitropyrimidin-4-amine (Intermediate 30, 1.0 g) and [(1S)-1-(5-fluoropyridin-2-yl)ethyl]amine hydrochloride (Intermediate 5, 0.8 g) in n-BuOH (5 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 1.0 g of the title compound. MS (electrospray): 403 (M+1) for C17H19FN8O3. 1H NMR (300 MHz, CD3OD) δ ppm 9.10 (s, 1H) 8.50 (s, 1H) 7.60 (m, 1H) 7.40 (m, 1H) 5.80 (s, 1H) 5.20 (m, 1H) 4.70 (m, 2H) 1.60 (d, 3H) 1.40 (d, 6H).
