Using a procedure similar to that described in Example 1, except using 2-amino-3-(6-bromo-2H-pyrazolo[4,3-b]pyridin-2-yl)-2-methylpropionitrile (223 mg described in Example 182) and 4-trifluoromethylthiobenzoyl chloride, the title compound was isolated as a white solid (145 mg, 38%). MS (ES): M/Z [M+H]=484. 1H NMR: (400 MHz, CHLOROFORM-d): 1.95 (s, 3H), 4.86 (d, J=14.0 Hz, 1H), 5.01 (d, J=14.1 Hz, 1H), 7.78 (d, J=8.3 Hz, 2H), 7.84-7.90 (m, 2H), 8.11 (s, 1H), 8.22 (dd, J=2.0, 1.0 Hz, 1H), 8.42 (d, J=0.8 Hz, 1H) and 8.64 (d, J=2.0 Hz, 1H). 19F NMR (376 MHz, CHLOROFORM-d): −42.2 (s, 3F).
