Reaction Steps

[8-(2-Methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-[3-(4-methyl-piperazin-1-yl)-phenyl]-amine was prepared from 8-(2-methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine (75.0 mg, 0.260 mmol) and 1-(3-bromo-phenyl)-4-methyl-piperazine (80.0 mg, 0.314 mmol) with 2,2′-bis-dicyclohexylphosphanyl-biphenyl (30.0 mg, 0.0549 mmol) as the ligand in a manner analogous to Step 2d and was isolated as a yellow foam (0.074 g, 62%). 1H NMR (400 MHz, CDCl3, δ, ppm): 8.49m (d, J=6.6 Hz, 1H), 8.24 (d, J=7.9 Hz, 1H), 7.74 (t, J=6.8 Hz, 1H), 7.67 (t, J=7.8 Hz, 1H), 7.49 (d, J=7.3 Hz, 2H), 7.29-7.25 (m, 1H), 7.19 (t, J=7.8 Hz, 1H), 6.99 (t, J=6.9 Hz, 1H), 6.90 (d, J=7.9 Hz, 1H), 6.73 (s, 1H), 6.57 (d, J=8.2 Hz, 1H), 3.24-3.19 (m, 4H), 2.96 (s, 3H), 2.59-2.54 (m, 4H), 2.36 (s, 3H). MS=463 (MH)+.
