Procedure
6-((6-Bromo-1H-benzo[d]imidazol-1-yl)methyl)-2-(methylthio)benzo[d]thiazole was synthesized as a yellow solid (701 mg, 70%) using a procedure analogous to that described in Step 3 of Example 41, substituting 5-bromo-N1-((2-(methylthio)benzo[d]thiazol-6-yl)methyl)benzene-1,2-diamine from the previous step for 4-bromo-5-methoxy-N1-((2-(methylthio)benzo[d]thiazol-6-yl)methyl)benzene-1,2-diamine used in Example 41.
