Reaction Steps

To 3.96 g of the thus obtained N-ethyl-N-(2-p-toluenesulfonyloxyethyl)-5-isoquinolinesulfonamide were added 1.25 g of hexylamine, 1.14 g of potassium carbonate and 20 ml of dioxane. The mixture thus obtained was heated in a pressure vessel at 110° C. for 72 hours, and then the dioxane was removed under reduced pressure to obtain a crude product. Then, 60 ml of dichloromethane was added to the crude product, and the mixture thus obtained was washed with 30 ml of water and dried with anhydrous magnesium sulfate. The dichloromethane was removed under reduced pressure to obtain a residue. The residue thus obtained was subjected to purification by silica gel column chromatography (Wacogel C-200, solvent: a 5% methanol solution in chloroform) to obtain 2.50 g of N-ethyl-N-(2-hexylaminoethyl)-5-isoquinolinesulfonamide [Compound (28)]. Compound (28) was analyzed to give the following data.
