A mixture of 5-cyclopropyl-N-(4,5-difluoro-2-nitrophenyl)-1H-pyrazol-3-amine (Method 86; 0.300 g, 1.07 mmol), (S)-1-(4-fluoro-phenyl)ethylamine (0.164 g, 1.18 mmol), and DIEA (0.280 ml, 1.61 mmol) in n-BuOH (2 ml) was heated in a sealed tube at 160° C. for 16 hrs. The solvent was removed under reduced pressure and the residue was purified by column chromatography (hexane:EtOAc=3:1) to give the title compound as an orange solid (0.360 g, 84%). NMR (400 MHz) 12.29 (s, 1H), 10.14 (s, 1H), 7.75 (d, J=12.8 Hz, 1H), 7.63 (d, J=6.4 Hz, 1H), 7.41 (m, 2H), 7.14 (t, J=8.8 Hz, 2H), 7.00 (d, J=8.0 Hz, 1H), 5.63 (s, 1H), 4.55 (m, 1H), 1.90 (m, 1H), 1.52 (d, J=6.8 Hz, 3H), 0.98 (m, 2H), 0.71 (m, 2H). MS: Calcd.: 399; Found: [M+H]+ 400.
