Procedure

300 mg (1.5 mmol) of isoquinoline-3-carboxylic acid and 570 mg (1.50 mmol) of HBTU were dissolved in 1.0 mL of DMF and 0.8 mL of DIEA and reacted with 110 mg (0.5 mmol) of 2-amino-7-methoxy-1H-benzoimidazole-4-carboxylic acid methyl 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 70 mg (37%) of 2-[(isoquinoline-3-carbonyl)-amino]-7-methoxy-3H-benzoimidazole-4-carboxylic acid methyl ester. LCMS: 378 (M+1)+.
