6-(4-Methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine was prepared from 6-bromo-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine (200.0 mg, 0.9388 mmol) and (4-methylsulfonylphenyl)boronic acid (210.0 mg, 1.050 mmol) in a manner analogous to Step 2c. The reaction product was isolated as an off-white solid (0.158 g, 58%). MP=301-303° C. 1H NMR (400 MHz, (D3C)2SO, δ, ppm): 9.08-9.05 (m, 1H), 8.06-7.97 (m, 4H), 7.86 (dd, J=9.2, 1.7 Hz, 1H), 7.48 (d, J=9.1 Hz, 1H), 6.15 (s, 2H), 3.26 (s, 3H). MS=289 (MH)+.
