Procedure
In 50 ml of a chloroform solution containing 1.4 g of 3-dimethylaminopropylamine and 1.4 g of triethylamine was added dropwise 30 ml of a chloroform solution containing 2.6 g of 5-isoquinolinesulfonyl chloride under cooling with ice. After the dropwise addition of the chloroform solution, the mixed solution was stirred at a temperature of 2° C. to 10° C. for four hours, and the reaction mixture solution was washed with water and dried with anhydrous magnesium sulfate. After the chloroform was distilled therefrom, the residue obtained was subjected to a silica gel column chromatography (silica gel: 70 g; solvent: chloroform) to give 2.38 g of N-(3-dimethylaminopropyl)-5-isoquinolinesulfonamide, i.e., Compound (17) in a yield of 71%.
