Reaction Steps

N-Methyl-N-(2-{2-[3-(1-methyl-piperidin-4-yl)-phenylamino]-[1,2,4]triazolo[1,5-a]pyridin-8-yl}-phenyl)-methanesulfonamide was prepared from N-[2-(2-amino-[1,2,4]triazolo[1,5-a]pyridin-8-yl)-phenyl]-N-methyl-methanesulfonamide (75.0 mg, 0.236 mmol) and 4-(3-bromo-phenyl)-1-methyl-piperidine; hydrochloride (76.0 mg, 0.262 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 pale yellow foam (0.099 g, 85%). 1H NMR (400 MHz, CDCl3, δ, ppm): 8.48 (dd, J=6.8, 0.9 Hz, 1H), 7.59-7.36 (m, 7H), 7.28-7.23 (m, 1H), 6.98 (t, J=7.1 Hz, 1H), 6.86 (d, J=7.6 Hz, 1H), 6.76 (s, 1H), 3.17 (s, 3H), 3.02-2.95 (m, 2H), 2.74 (s, 3H), 2.53-2.43 (m, 1H), 2.34 (s, 3H), 2.10-2.00 (m, 2H), 1.89-1.78 (m, 4H). MS=491 (MH)+.
