Reaction Steps

1-[({4-Chloro-1-guanidino-7-isoquinolinyl}sulphonyl)amino]-N-(2-methoxyethyl)cyclopentanecarboxamide hydrochloride ##STR87## 1-[({4-Chloro-1-guanidino-7-isoquinolinyl}sulphonyl)amino]-N-(2-methoxyethyl)cyclopentanecarboxamide was prepared from 2-methoxyethylamine and 1-{[(4-chloro-1-guanidino-7-isoquinolinyl)sulphonyl]amino}cyclopentanecarbonyl chloride, following the same procedure described in example 76. This product was treated with ethereal HCl (1N) and the mixture evaporated in vacuo. The residual solid was dissolved in EtOH, water (1 drop) added, the solution concentrated in vacuo until precipitation occured, and the resulting solid filtered, washed with Et2O, and dried under vacuum, at 50° C., to afford 1-[({4-chloro-1-guanidino-7-isoquinolinyl}sulphonyl)amino]-N-(2-methoxyethyl)cyclopentanecarboxamide hydrochloride (35 mg, 28%).
