Procedure

25 mg (0.049 mmol) of 1,2,3,4-tetrahydro-isoquinoline-6-carboxylic acid [4-(1H-imidazol-2-ylcarbamoyl)-1H-benzoimidazol-2-yl]-amide, 0.01 mL of (0.07 mmol) benzenesulfonyl chloride, and 0.07 mL of (0.5 mmol) triethylamine in 0.5 mL DMF was stirred at room temperature for 1 h. The reaction mixture was then treated with 0.024 mL of hydrazine hydrate and diluted with water. The precipitated solid was filtered and washed with water to give 2-benzenesulfonyl-1,2,3,4-tetrahydro-isoquinoline-6-carboxylic acid [4-(1H-imidazol-2-ylcarbamoyl)-1H-benzoimidazol-2-yl]-amide (17.2 mg, 65%). LCMS: 542 (M+1)+.
