Procedure

300 mg (0.75 mmol) of 6-benzyloxy-2-[(isoquinoline-3-carbonyl)-amino]-3H-benzoimidazole-4-carboxylic acid and 600 mg (1.58 mmol) of HBTU were dissolved in 2.0 mL of DMF and 1.0 mL of DIEA and reacted with 390 mg (3.0 mmol) of 2-aminoimidazole sulfate as described in general procedure A. Upon completion, the reaction was diluted with brine. The resulting solid was filtered, washed with water and EtOAc, and dried under vacuum to produce 300 mg (80%) of isoquinoline-3-carboxylic acid [5-benzyloxy-7-(1H-imidazol-2-ylcarbamoyl)-1H-benzoimidazol-2-yl]-amide. LCMS: 505 (M+1)+.
