Reaction Steps

1.42 g (8 mmol) of above 7-nitro-1H-benzoimidazol-2-ylamine was reacted with 1.38 g (8 mmol) of isoquinoline-3-carboxylic acid, 3.4 g (9 mmol) of HBTU in 30.0 mL of DMF and 5.0 mL of DIEA as described in general procedure A. After cooling to room temperature, the reaction mixture was diluted with 60 mL of saturated NaHCO3 and 100 mL of water. The solid was collected by filtration and washed with water and dried under reduced pressure, and subsequently subjected to hydrogenation as described in general procedure C to give 1.0 g (41%) of the isoquinoline-3-carboxylic acid (7-amino-1H-benzoimidazol-2-yl)-amide.
