Procedure

0.05 (0.23 mmol) of the above synthesized 4-phenylethynyl-pyridine-2-carboxylic acid, 0.095 g (0.25 mmol) of HBTU in a mixture of 2.0 ml of DMF and 0.20 mL of DIEA was reacted with 0.05 g (0.20 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. 5.0 mL of water and 5.0 mL of saturated NaHCO3 was added, and the resulting solid was filtered. The solid was washed with water and ether, and dried to provide 0.04 g (43%) of 2-[(4-phenylethynyl-pyridine-2-carbonyl)-amino]-1H-benzoimidazole-4-carboxylic acid (1H-imidazol-2-yl)-amide. LCMS: 448 (M+1)+.
