Procedure
To a solution of ((5-aminobenzimidazol-2-yl)(4-bromophenylamine (1 eq) in N,N-dimethylformamide was added sodium hydride (2 eq) and the mixture was microwaved for 8 mins at 220° C. The reaction mixture was partitioned between ethyl acetate and water and the organic layer was dried with sodium sulfate and concentrated. Preparative chromatography yielded [4-({2-[(4-bromophenyl)amino}benzimidazol-5-yl}amino)(2-pyridyl-N-methylcarboxamide. MS: MH+=437.
