Reaction Steps

A solution of NaOH (5 mL, 2 M, 10 mmol) was added to a solution of ethyl 1-{[(4-chloro-1-guanidino-7-isoquinolinyl)sulphonyl]amino)cyclobutanecarboxylate (100 mg, 0.23 mmol) in MeOH (5 mL) and the mixture was heated at 55° C. for 6 h. The cooled mixture was neutrilised with dilute HCl (5 mL, 2 M) to give a precipitate and the MeOH was evaporated in vacuo. The solid was collected by filtration, with copious water washing, and dried under high vacuum to give 1-{[(4-chloro-1-guanidino-7-isoquinolinyl)sulphonyl]amino}cyclobutanecarboxylic acid hydrochloride (15 mg, 0.033 mmol).
