Procedure

In 100 ml of ethanol was dissolved 2.0 g of N-[2-(N-methyl-N-benzylamino)ethyl]-5-isoquinolinesulfonamide, i.e., Compound (65) as obtained in Example 16, and to the solution was added 0.2 g of 10% palladium-carbon. Then the solution was vigorously stirred at a temperature of 20° C. to 25° C. in a hydrogen stream of 2.0 to 2.5 atm. for 5 hours. After the palladium-carbon was separated from the reaction solution by filtration, the reaction solution was concentrated to dryness to give 0.95 g of N-(2-methylaminoethyl)-5-isoquinolinesulfonamide, i.e., Compound (14) in a yield of 64%.
