Reaction Steps

N(8)-(2-Methoxy-benzyl)-N(2)-pyridin-3-yl-[1,2,4]triazolo[1,5-a]pyridine-2,8-diamine was prepared from 3-aminopyridine (36.47 mg, 0.3875 mmol) and (2-chloro-[1,2,4]triazolo[1,5-a]pyridin-8-yl)-(2-methoxy-benzyl)-amine (99.9 mg, 0.346 mmol) in a manner analogous to Example 2d. Product isolated as an off-white foam (19.21 mg, 16%). 1H NMR (400 MHz, (D3C)2SO, δ, ppm): 9.68 (s, 1H), 8.88 (s, 1H), 8.21 (d, J=8.6 Hz, 1H), 8.09 (s, 1H), 7.99 (d, J=7.5 Hz, 1H), 7.33-7.20 (m, 3H), 7.03 (d, J=8.6 Hz, 1H), 6.87 (t, J=15.2, 8.1 Hz, 1H), 6.77 (t, J=13.5, 6.6 Hz, 1H), 6.31 (m, 2H), 4.47 (d, J=5.8 Hz, 2H), 3.87 (s, 3H).
