Versuchsvorschrift

To a solution of 44 mg (0.2 mmol) of 7-nitro-isoquinoline-3-carboxylic acid in DMF (1 mL) was added 113 mg (0.3 mmol) of HBTU and DIEA (0.3 mL). The mixture was stirred for 10 min and then 40 mg (0.16 mmol) of 2-amino-3H-benzoimidazole-4-carboxylic acid (1H-imidazol-2-yl)-amide (intermediate B) was added. The reaction was heated at 80° C. for 1 h. After the usual work up, the residue was purified by column chromatography eluting with DCM/methanol (v/v=10:1) to afford 8 mg (9%) of 7-nitro-isoquinoline-3-carboxylic acid [7-(1H-imidazol-2-ylcarbamoyl)-1H-benzoimidazol-2-yl]-amide. LCMS: 443 (M+1)+.
