Reaktionsschritte

60 mg (0.15 mmol) of 6-ethoxy-7-fluoro-2-[(isoquinoline-3-carbonyl)-amino]-3H-benzoimidazole-4-carboxylic acid (from Example 485) and 100 mg (0.25 mmol) of HBTU were dissolved in 1.0 mL of DMF and 0.2 mL of DIEA and treated with 50 mg (0.5 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 32 mg (46%) of Isoquinoline-3-carboxylic acid [5-ethoxy-4-fluoro-7-(1H-imidazol-2-ylcarbamoyl)-1H-benzoimidazol-2-yl]-amide. LCMS: 460 (M+1)+.
