実験手順

600 mg (3.0 mmol) of isoquinoline-3-carboxylic acid and 1200 mg (3.1 mmol) of HBTU were dissolved in 3.0 mL of DMF and 0.6 mL of DIEA and reacted with 500 mg (2.0 mmol) of 2-amino-6-ethoxy-1H-benzoimidazole-4-carboxylic acid ethyl ester 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 500 mg (62%) of 6-ethoxy-2-[(isoquinoline-3-carbonyl)-amino]-3H-benzoimidazole-4-carboxylic acid ethyl ester. LCMS: 406 (M+1)+.
