A mixture of 6-chloro-N-(5-isopropoxy-1H-pyrazol-3-yl)-3-nitropyridin-2-amine (Intermediate 7, 0.5 g) and [(15)-1-(5-fluoropyridin-2-yl)propyl]amine (Intermediate 35, 0.45 g) in n-BuOH (10 mL) with diisopropylethylamine (3 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 0.45 g of desired product. MS (electrospray): 416 (M+1) for C19H22FN7O3.
