Procedure
[8-(4-Methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-[4-(4-methyl-piperazin-1-ylmethyl)-phenyl]-amine was prepared from 8-(4-methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine (50.0 mg, 0.173 mmol) and 1-(4-bromo-benzyl)-4-methyl-piperazine (56.0 mg, 0.208 mmol) with 2,2′-bis-dicyclohexylphosphanyl-biphenyl (20.0 mg, 0.0366 mmol) as the ligand in a manner analogous to Step 2d and was isolated as a pale yellow foam (0.010 g, 12%). 1H NMR (400 MHz, CDCl3, δ, ppm): 8.50 (d, J=6.4 Hz, 1H), 8.24 (d, J=8.2 Hz, 2H), 8.09 (d, J=8.2 Hz, 2H), 7.66 (d, J=7.1 Hz, 1H), 7.54 (d. J=7.8 Hz, 2H), 7.31 (d, J=7.9 Hz, 2H), 7.02 (t, J=6.7 Hz, 1H), 6.86 (s, 1H), 3.49 (s, 2H), 3.11 (s, 3H), 2.46 (br s, 8H), 2.29 (s, 3H). MS=477 (MH)+.
