Methanaminium, N-((1H-benzotriazol-1-yloxy)(dimethylamino)methylene)-N-methyl-, hexafluorophosphate(1-) (1:1) → HCID 58026485, compound

Participants

Reaction Steps

100 mg (0.56 mmol) of the 2-methyl-1,8a-dihydro-imidazo[1,2-a]pyridine-3-carboxylic acid and 234 mg (0.61 mmol) of HBTU in a mixture of 1.5 mL of DMF and 0.6 mL of DIEA was reacted with 137 mg (0.56 mmol) of the 2-amino-3H-benzoimidazole-4-carboxylic acid (1H-imidazol-2-yl)-amide (Intermediate B) as described in general procedure A. After the reaction was complete, it was diluted with brine (20 mL), and the resulting solid was filtered, washed with water, ethyl acetate and dried under vacuum to give 40 mg (17%) of 2-[(2-methyl-imidazo[1,2-a]pyridine-3-carbonyl)-amino]-1H-benzoimidazole-4-carboxylic acid (1H-imidazol-2-yl)-amide as a solid. LCMS: 401 (M+1)+.
