Reaction Steps

5-{4-[(1,1-dioxidothiomorpholin-4-yl)methyl]phenyl}-N-[3-(4-methylpiperazin-1-yl)phenyl][1,2,4]triazolo[1,5-a]pyridin-2-amine was prepared from 5-{4-[(1,1-dioxidothiomorpholin-4-yl)methyl]phenyl}[1,2,4]triazolo[1,5-a]pyridin-2-amine (75.0 mg, 0.210 mmol) and 1-(3-bromo-phenyl)-4-methyl-piperazine (65.0 mg, 0.255 mmol) with 2,2′-bis-dicyclohexylphosphanyl-biphenyl (22.0 mg, 0.0402 mmol) as the ligand in a manner analogous to Step 2d and was isolated as an off-white solid (0.052 g, 47%).
