Procedure

5-cyano-1-(3-(2thiazolyl)phenyl)benzimidazole was synthesized as described in Example 34 by using (31) (2.0 g, 5.9 mmol) instead of 5-acetyl-1-(3-bromophenyl)benzimidazole, (PPh3)2PdCl2 (100 mg, 0.14 mmol) and 2-(tributylstannyl)thiazole (3.6 g, 9.7 mmol). The reaction gave 5-cyano-1-(3-(2-thiazolyl)phenyl)benzimidazole (1.5 g, 86%).
