Hydrochloric Acid → HCID 178478822, compound

Participants

Reaction Steps

In 20 ml of methanol was suspended 1.0 g of N-(2-guanidinoethyl)-5-isoquinolinesulfonamide, i.e., Compound (2), the crystalline residue was dissolved with 7.5 ml of 1N aqueous hydrochloride solution. The reaction mixture solution was condensed to dryness under reduced pressure, the crystalline residue thus obtained was recrystallized from methanol to give 1.12 g of N-(2-guanidinoethyl)-5-isoquinolinesulfonamide dihydrochloride in a yield of 90%.
