A mixture of 6-chloro-N-(5-isopropoxy-1H-pyrazol-3-yl)-3-nitropyridin-2-amine (Method 28, 0.33 g, 1.1 mmol), (S)-1-(4-fluoro-phenyl)-ethylamine (0.16 g, 1.2 mmol) and DIEA (0.21 ml, 1.2 mmol) in n-BuOH (3 ml) was heated in a sealed tube at 165° C. for 4 hours. The solvent was removed under reduced pressure and the residue was purified by column chromatography (hexane-EtOAc=1:1) to give the title compound as a yellow solid (0.43 g, 97%). 1H NMR (400 MHz) δ 12.09, 12.05 & 11.64 (s, 1H), 10.94, 10.87 & 10.72 (s, 1H), 8.98, 8.76 & 8.70 (d, J=7.6 Hz, 1H), 8.16 & 8.11 (d, J=9.6 Hz, 1H), 7.40-7.33 (m, 2H), 7.22-7.10 (m, 2H), 6.25 & 6.04 (d, J=9.6 Hz, 1H), 6.23 & 5.86 (d, J=13.6 Hz, 1H), 5.31, 5.21 & 4.89 (m, 1H), 4.71, 4.59 & 4.27 (m, 1H), 1.52 (m, 3H), 1.26 (m, 6H). MS: Calcd.: 400. Found: [M+H]+ 401.
