3-(6-Methoxy-2-benzimidazolyl)benzothiazolin-2-imine

The title compound, C₁₅H₁₂N₄OS, was unexpectedly isolated from the reaction of N-[2-(1H-benzimidazol-2-ylthio)phenyl]thiourea with dicyclohexylcarbodiimide. The compound showed considerable anti-cancer activity in vitro. Benzimidazole and iminobenzothiazoline rings are coplanar via the hydrogen bonding between the N atom of the imino group of benzothiazole and the H-N bond of benzimidazole. The whole molecule has a planar structure.
