Reaction Steps

[8-(4-Methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-[3-(4-methyl-piperazin-1-ylmethyl)-phenyl]-amine was prepared from 8-(4-methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine (75.0 mg, 0.260 mmol) and 1-(3-bromo-benzyl)-4-methyl-piperazine (77.0 mg, 0.286 mmol) with 2,2′-bis-dicyclohexylphosphanyl-biphenyl (29.0 mg, 0.0530 mmol) as the ligand in a manner analogous to Example 2d. Product isolated as a yellow foam (0.036 g, 29%). 1H NMR (400 MHz, CDCl3, δ, ppm): 8.51 (d, J=6.6 Hz, 1H), 8.24 (d, J=8.5 Hz, 2H), 8.09 (d, J=8.5 Hz, 2H), 7.66 (dd, J=7.4, 0.9 Hz, 1H), 7.58 (dd, J=7.8, 1.9 Hz, 1H), 7.46 (s, 1H), 7.31 (t, J=7.8 Hz, 1H), 7.02 (t, J=7.2 Hz, 1H), 6.98 (d, J=7.5 Hz, 1H), 6.90 (s, 1H), 3.54 (s, 2H), 3.10 (s, 3H), 2.70-2.32 (m, 8H), 2.29 (s, 3H). MS=477 (MH)+.
