反应详情

584 μL (3 mmol) of triethylamine and 208 mg (1.68 mmol) of 2 methylamino-acetamide are added to 456 mg (1.4 mmol) of 8-chlorosulfonyl-4-oxo-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-carboxylic acid suspended in 4 mL of anhydrous dichloromethane and 1 mL of anhydrous dimethylformamide. The reaction mixture is stirred for 3 days at room temperature. The solvents are evaporated then the residue is taken up in methanol. The solid is filtered, rinsed with methanol then diisopropyl ether and dried under vacuum to give 279 mg (53%) of 8-(carbamoylmethyl-methyl-sulfamoyl)-4-oxo-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-carboxylic acid in the form of a white solid.
