Procedure

0.15 g (0.45 mmol) of 2-[(isoquinoline-3-carbonyl)-amino]-1H-benzoimidazole-5-carboxylic acid was reacted with 0.26 g (0.68 mmol) of HBTU and 0.06 g (0.45 mmol) of 2-aminoimidazole sulfate in 3.0 mL of DMF and 1.0 mL of DIEA as described in general procedure A. After cooling to room temperature, the reaction mixture was diluted with water, the solid was collected by filtration, dissolved with MeOH and evaporated onto silica gel, and isolated by flash column chromatography (500 mL DCM/20 mL NH3/MeOH) to yield ˜10 mg of the desired isoquinoline-3-carboxylic acid [5-(1H-imidazol-2-ylcarbamoyl)-1H-benzoimidazol-2-yl]-amide. LCMS: 398.0 (M+1)+
