Procedure

A mixture of 5-cyclopropyl-N-(2,3-difluoro-6-nitrophenyl)-1H-pyrazol-3-amine (Method 85; 0.400 g, 1.43 mmol), (S)-1-(4-fluoro-phenyl)ethylamine (0.209 g, 1.50 mmol, and DIEA (0.373 ml, 2.14 mmol) in n-BuOH (3 ml) was heated in a sealed tube at 160° C. for 8 hours. The solvent was removed under reduced pressure and the residue was purified by column chromatography (hexane:EtOAc=4:1) to give the title compound as an orange solid (0.40 g, 70%). NMR (400 MHz) 11.95 (s, 1H), 8.74 (s, 1H), 7.72 (d, J=9.2 Hz, 1H), 7.43 (t, J=7.0 Hz, 2H), 7.25 (d, J=6.4 Hz, 1H), 7.15 (t, J=8.8 Hz, 2H), 6.26 (t, J=8.6 Hz, 1H), 5.63 (s, 1H), 4.78 (m, 1H), 1.84 (m, 1H), 1.48 (d, J=6.8 Hz, 3H), 0.91 (m, 2H), 0.66 (m, 2H). MS: Calcd.: 399; Found: [M+H]+ 400.
