Versuchsvorschrift

0.12 g (0.51 mmol) of 6-(3-cyano-phenyl)-pyridine-2-carboxylic acid, 0.19 g (0.5 mmol) of HBTU in a mixture of 2.0 ml of DMF and 0.26 mL of DIEA was reacted with 0.1 g (0.41 mmol) of 2-amino-3H-benzoimidazole-4-carboxylic acid (1H-imidazol-2-yl)-amide (Intermediate B) as described in general procedure A. The reaction mixture was cooled to r.t. and 5.0 mL of water and 5.0 mL of saturated NaHCO3 was added. The resulting solid was filtered, and the solid was washed with water and ether and dried to provide 0.04 g (17.5%) of 2-{[6-(3-cyano-phenyl)-pyridine-2-carbonyl]-amino}-1H-benzoimidazole-4-carboxylic acid (1H-imidazol-2-yl)-amide. 1H-NMR (400 MHz, DMSO): 9.15 (s, 1H), 8.86 (s, 1H), 8.45(m, 1H), 8.24 (m, 2H), 7.99 (d, 1H), 7.92 (d, 1H), 7.87 (d, 1H), 7.72 (t, 1H), 7.41(t, 1H), 7.30 (s, 2H) ppm. LCMS: 449 (M+1)+.
