5-(2-Methoxy-5-trifluoromethyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridine-2yl-amine was prepared from 5-bromo-[1,2,4]triazolo[1,5-a]pyridine-2-yl-amine (0.5 g, 2.3 mmol), and 2-methoxy-5-trifluoromethylbenzeneboronic acid (0.76 g, 3.4 mmol) in a manner analogous to Example 2c. Product was isolated as a foam (0.63 g, 87%). 1H NMR (400 MHz, CDCl3, δ, ppm): 7.79-7.73 (m, 2H), 7.49-7.44 (m, 2H), 7.15 (d, J=8.9 Hz, 1H), 6.85 (t, J=4.2 Hz, 1H), 4.45 (brs, 2H), 3.85 (s, 3H). MS=309 (MH)+.
