Reaction Steps

N(8)-(2-Methanesulfonyl-benzyl)-N(2)-[3-(4-methyl-piperazin-1-yl)-phenyl]-[1,2,4]triazolo[1,5-a]pyridine-2,8-diamine was prepared from (2-chloro-[1,2,4]triazolo[1,5-a]pyridin-8-yl)-(2-methanesulfonyl-benzyl)-amine (75.0 mg, 0.223 mmol) and 3-(4-methylpiperazin-1-yl)aniline (47.0 mg, 0.246 mmol) with 2,2′-bis-dicyclohexylphosphanyl-biphenyl (25.0 mg, 0.0457 mmol) as the ligand in a manner analogous to Example 2d.
