Procedure

To 75 ml of an anhydrous methanol solution containing 5.89 g of the thus obtained N-acetonyl-N-hexyl-5-isoquinolinesulfonamide were added 13.03 g of ammonium acetate and 0.75 g of sodium cyanoborohydride, followed by stirring at 15° to 20° C. for 19 hours. Then, the methanol was removed at 30° C. under reduced pressure. To the resultant reaction product were added 50 ml of chloroform and 50 ml of 1N sodium hydroxide solution. The chloroform layer was dried with anhydrous magnesium sulfate, and the chloroform 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, 100 g; solvent: chloroform) to obtain 2.75 g of N-(2-aminopropyl)-N-hexyl-5-isoquinolinesulfonamide [Compound (11)]. Compound (11) was analyzed to give the following data.
