Procedure
1-(4-{3-[8-(4-Methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-ylamino]-phenyl}-piperazin-1-yl)-2-methyl-propan-2-ol was prepared from 2-chloro-8-(4-methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridine (100.0 mg, 0.3249 mmol) and 1-[4-(3-amino-phenyl)-piperazin-1-yl]-2-methyl-propan-2-ol (89.0 mg, 0.357 mmol) with 2,2′-bis-dicyclohexylphosphanyl-biphenyl (36.0 mg, 0.0658 mmol) as the ligand in a manner analogous to Example 2d. Product isolated as a yellow foam (0.117 g, 68%). 1H NMR (400 MHz, CDCl3, δ, ppm): 8.49 (d, J=6.1 Hz, 1H), 8.25 (d, J=8.4 Hz, 2H), 8.07 (d, J=8.4 Hz, 2H), 7.66 (d, J=7.4 Hz, 1H), 7.37 (s, 1H), 7.22 (t, J=8.2 Hz, 1H), 7.02 (t, J=7.0 Hz, 1H), 6.96 (dd, J=8.1, 1.3 Hz, 1H), 6.88 (s, 1H), 6.59 (dd, J=8.1, 1.7 Hz, 1H), 3.29-3.23 (m, 4H), 3.10 (s, 3H), 2.87-2.81 (m, 4H), 2.42 (s, 2H), 1.22 (s, 6H). MS=521 (MH)+.
