Reaction Steps
(2-Chloro-[1,2,4]triazolo[1,5-a]pyridin-8-yl)-(3-methanesulfonyl-phenyl)-amine was prepared from 8-bromo-2-chloro-[1,2,4]triazolo[1,5-a]pyridine (250.0 mg, 1.075 mmol) and 3-methanesulfonyl-phenylamine; hydrochloride (245.0 mg, 1.180 mmol) in a manner analogous to Example 2d. Product was isolated as a pale yellow solid (0.268 g, 77%). 1H NMR (400 MHz, CDCl3, δ, ppm): 8.10 (d, J=6.7 Hz, 1H), 7.87 (s, 1H), 7.64 (d, J=7.6 Hz, 1H), 7.58 (t, J=8.0 Hz, 1H), 7.46 (d, J=7.7 Hz, 1H), 7.30-7.25 (m, 1H), 7.03 (s, 1H), 6.99 (t, J=6.9 Hz, 1H), 3.09 (s, 3H). MS=323, 325 (MH)+. 109b) N(8)-(3-Methanesulfonyl-phenyl)-N(2)-[4-(4-methyl-piperazin-1-yl)-phenyl]-[1,2,4]triazolo[1,5-a]pyridine-2,8-diamine was prepared from (2-chloro-[1,2,4]triazolo[1,5-a]pyridin-8-yl)-(3-methanesulfonyl-phenyl)-amine (75.0 mg, 0.232 mmol) and 4-(4-methyl-piperazin-1-yl)-phenylamine (50.0 mg, 0.261 mmol) with 2,2′-bis-dicyclohexylphosphanyl-biphenyl (25.0 mg, 0.0457 mmol) as the ligand in a manner analogous to Example 2d. Product isolated as a tan foam (0.009 g, 8%). 1H NMR (400 MHz, CDCl3, δ, ppm): 8.02 (d, J=6.2 Hz, 1H), 7.81 (s, 1H), 7.59-7.43 (m, 5H), 7.20 (d, J=8.0 Hz, 1H), 6.97 (d, J=7.5 Hz, 2H), 6.85 (s, 1H), 6.79 (t, J=7.4 Hz, 1H), 6.59 (s, 1H), 3.19-3.14 (m, 4H), 3.07 (s, 3H), 2.62-2.57 (m, 4H), 2.36 (s, 3H). MS=478 (MH)+.
