8-(6-Methoxy-pyridin-3-yl)-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine was prepared from 8-bromo-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine (1.0 g, 4.7 mmol) and 2-methoxypyridine-5-boronic acid (1.0 g, 6.6 mmol) in a manner analogous to Step 2c. The product of the reaction was isolated as a tan solid (0.58 g, 51%). MP=157-158° C. 1H NMR (400 MHz, (D3C)2SO, δ, ppm): 8.91 (d, J=2.5 Hz, 1H), 8.54 (dd, J=6.6, 0.9 Hz, 1H), 8.44 (dd, J=8.7, 2.5 Hz, 1H), 7.73 (dd, J=7.6, 1.0 Hz, 1H), 6.97 (t, J=6.9 Hz, 1H), 6.96 (d, J=8.7 Hz, 1H), 6.12 (s, 2H), 3.92 (s, 3H). MS=242 (MH)+.
