Reaction Steps

235 mg (1.0 mmol) of 6,7-dimethoxy-isoquinoline-3-carboxylic acid and 400 mg (1.0 mmol) of HBTU were dissolved in 1.5 mL of DMF and 0.5 mL of DIEA and treated with 249 mg (1.0 mmol) of 2-amino-6-ethoxy-1H-benzoimidazole-4-carboxylic acid ethyl ester (prepared in Example 471) 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 290 mg (0.63 mmol, 63%) of 2-[(6,7-dimethoxy-isoquinoline-3-carbonyl)-amino]-6-ethoxy-1H-benzoimidazole-4-carboxylic acid ethyl ester. LCMS: 465 (M+1)+.
