Procedure

300 mg (3.0 mmol) of the above 8-methoxy-imidazo[1,2-a]pyridine-2-carboxylic acid and 200 mg (0.5 mmol) of HBTU in a mixture of 1.5 mL of DMF and 0.6 mL of DIEA was reacted with 60 mg (0.25 mmol) of the 2-amino-3H-benzoimidazole-4-carboxylic acid (1H-imidazol-2-yl)-amide (Intermediate B) as described in general procedure A. After the reaction was complete, it was diluted with brine (20 mL), and the resulting solid was filtered, washed with water, ethyl acetate and dried under vacuum to give 41 mg (40%) of 2-[(8-methoxy-imidazo[1,2-a]pyridine-3-carbonyl)-amino]-1H-benzoimidazole-4-carboxylic acid (1H-imidazol-2-yl)-amide as a solid. LCMS: 417 (M+1)+.
