Reaction Steps
171 c) N-[2-(2-Chloro-[1,2,4]triazolo[1,5-a]pyridin-8-ylamino)-benzyl]-N-methyl-methanesulfonamide was prepared from 8-bromo-2-chloro-[1,2,4]triazolo[1,5-a]pyridine (500.0 mg, 2.151 mmol) and N-(2-amino-benzyl)-N-methyl-methanesulfonamide (507.0 mg, 2.366 mmol) in a manner analogous to Example 2d. Product isolated as a tan foam (0.53 g, 67%). 1H NMR (400 MHz, CDCl3, δ, ppm): 8.01 (d, J=6.4 Hz, 1H), 7.48-7.41 (m, 2H), 7.38 (t, J=7.4 Hz, 1H), 7.21 (t, J=7.4 Hz, 1H), 7.10 (s, 1H), 6.90-6.81 (m, 2H), 4.36 (s, 2H), 3.02 (s, 3H), 2.76 (s, 3H). MS=366 (MH)+. 171 d) N-Methyl-N-(2-{2-[4-(4-methyl-piperazin-1-yl)-phenylamino]-[1,2,4]triazolo[1,5-a]pyridin-8-ylamino}-benzyl)-methanesulfonamide was prepared from N-[2-(2-chloro-[1,2,4]triazolo[1,5-a]pyridin-8-ylamino)-benzyl]-N-methyl-methanesulfonamide (75.0 mg, 0.205 mmol) and 4-(4-methyl-piperazin-1-yl)-phenylamine (44.0 mg, 0.230 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 brown foam (0.019 g, 18%). 1H NMR (400 MHz, CDCl3, δ, ppm): 7.94 (d, J=6.5 Hz, 1H), 7.51 (d, J=8.7 Hz, 2H), 7.45-7.39 (m, 2H), 7.35 (t, J=7.2 Hz, 1H), 7.13 (t, J=7.4 Hz, 1H), 7.00-6.94 (m, 3H), 6.81 (d, J=7.7 Hz, 1H), 6.68 (t, J=7.2 Hz, 1H), 6.60 (s, 1H), 4.36 (s, 2H), 3.18-3.13 (m, 4H), 2.91 (s, 3H), 2.78 (s, 3H), 2.62-2.57 (m, 4H), 2.36 (s, 3H). MS=521 (MH)+.
