Benzenesulfonyl chloride → HCID 178522493, compound

Participants

Reaction Steps

66 mg (0.2 mmol) of isoquinoline-3-carboxylic acid (4-amino-1H-benzoimidazol-2-yl)-amide was dissolved in pyridine (0.6 mL). To this stirred solution at 0° C., 0.2 mmol of phenylsulfonyl chloride in 0.2 mL of DCM was added in one portion. The reaction mixture was stirred at room temperature for 2 h. Brine (5 mL) was added and stirred for 10 min. The resulting solid was collected by filtration, washed with water (3×2 ml) and EtOAc (3×3 mL) and dried to yield 46 mg (52%) of isoquinoline-3-carboxylic acid (7-benzenesulfonylamino-1H-benzoimidazol-2-yl)-amide. LCMS: 444 (M+1)+.
