Reaction Steps
(2-Chloro-[1,2,4]triazolo[1,5-a]pyridin-8-yl)-(4-methoxy-benzyl)-amine was prepared from 8-bromo-2-chloro-[1,2,4]triazolo[1,5-a]pyridine (2.00 g, 8.60 mmol), and 4-methoxy-benzenemethanamine, (1.26 mL, 9.72 mmol) in a manner analogous to Example 2d. Product isolated as an off-white solid, (1.51 g. 61%). 1H NMR (400 MHz, (D3C)2SO, δ, ppm): 8.06 (d, J=6.90 Hz, 1H), 7.31 (d, J=8.2 Hz, 2H), 7.19 (m, 1H), 6.94 (t, J=14.4, 7.6 Hz, 1H), 6.87 (d, J=7.4 Hz, 2H), 6.42 (d, J=8.0 Hz, 1H), 4.40 (d, J=6.1 Hz, 2H), 3.71 (s, 3H). MS=289 (MH)+. 391b) N(8)-(4-Methoxy-benzyl)-N(2)-[4-(4-methyl-piperazin-1-yl)-phenyl]-[1,2,4]triazolo[1,5-a]pyridine-2,8-diamine was prepared from 4-(4-methyl-piperazin-1-yl)-phenylamine (74.2 mg, 0.388 mmol) and (2-chloro-[1,2,4]triazolo[1,5-a]pyridin-8-yl)-(4-methoxy-benzyl)-amine (99.9 mg, 0.346 mmol) in a manner analogous to Example 2d. Product was isolated as a red foam (10.64 mg, 7%). 1H NMR (400 MHz, (D3C)2SO, δ, ppm): 9.03 (s, 1H), 7.92 (d, J=6.2 Hz, 1H), 7.56 (d, J=8.3 Hz, 2H), 7.32 (d, J=7.8 Hz, 2H), 6.88 (d, J=8.3 Hz, 4H), 6.68 (t, J=13.9, 7.0 Hz, 1H), 6.29 (m, 2H), 4.42 (m, 2H), 3.72 (s, 3H), 3.03 (s, 4H), 2.47 (s, 4H), 2.22 (s, 3H).
