Reaction Steps
To a solution of [4-(2-{[4-(chloromethyl)phenyl]carbonylamino)-1-methylbenzimidazol-5-yloxy)(2-pyridyl)]-N-methylcarboxamide (1 eq) in tetrahydrofuran was added methylpiperazine (4 eq) and stirred at ambient temperature for 16 h. The reaction mixture was concentrated and purified on preparative chromatography to yield N-methyl {4-[1-methyl-2-({4-[(4-methylpiperazinyl)methyl]phenyl}carbonylamino)benzimidazol-5-yloxy](2-pyridyl)}carboxamide. MS: MH+=512.
