Reaction Steps

8-(2-Methoxy-phenyl)-[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, 0.0047 mol) and 2-methoxybenzeneboronic acid (1.1 g, 0.0070 mol) in a manner analogous to Step 2c. The reacting product was isolated as a brown solid (1.0 g) and was used without further purification. 1H NMR (400 MHz, (D3C)2SO, δ, ppm): 8.50 (d, J=6.5 Hz, 1H), 7.51 (dd, J=7.6, 1.5 Hz, 1H), 7.43-7.36 (m, 2H), 7.13 (d, J=8.1 Hz, 1H), 7.02 (t, J=7.3 Hz, 1H), 6.91 (t, J=7.0 Hz, 1H), 5.96 (br s, 2H), 3.73 (s, 3H). MS=241 (MH)+.
