실험 절차

To a stirring mixture of 1.0 g (5.2 mmol) of 2-amino-3H-benzoimidazole-4-carboxylic acid methyl ester (Intermediate A) and 0.86 g (5.2 mmol) of CDI in 3.0 mL of DMF was added 0.75 g (5.2 mmol) of Isoquinolin-3-ylamine. The reaction mixture was heated at 60° C. for 30 min, and then cooled to room temperature. 5.0 mL of water was added. The resulting solid was filtered washed with water (10 ml) and ether (10 mL), and dried to provide the 2-(3-isoquinolin-3-yl-ureido)-1H-benzoimidazole-4-carboxylic acid methyl ester as a solid which was hydrolyzed as described in general procedure B to provide 0.75 g (40%) of 2-(3-isoquinolin-3-yl-ureido)-1H-benzoimidazole-4-carboxylic acid. LCMS: 348 (M+1)+.
