Procedure

To a solution of 48.4 mg (0.2 mmol) of 2-amino-3H-benzoimidazole-4-carboxylic acid (1H-imidazol-2-yl)-amide (Intermediate B) in dry DMF (1.0 mL) was added 49 mg (0.3 mmol) of di-imidazol-1-yl-methanone in one portion. The mixture was heated at 50° C. for 30 min, after cooling to room temperature, 23 mg (0.16 mmol) of isoquinolin-3-ylamine was added to the reaction mixtures. The reaction mixture was stirred at 45° C. for 45 min. After cooling to r.t., the organic solvent was removed under reduced pressure. The residue was purified by column chromatography eluting with DCM/methanol (v/v=10:1 to 8:1) to give 17 mg (20%) of 2-(3-isoquinolin-3-yl-ureido)-1H-benzoimidazole-4-carboxylic acid (1H-imidazol-2-yl)-amide. LCMS: 413 (M+1)+.
