Procedure
N-[(4-Chloro-1-guanidino-7-isoquinolinyl)sulphonyl]-N-(3-pyridylmethyl)glycine dihydrochloride ##STR26## Guanidine hydrochloride (317 mg, 3.32 mmol was added in one portion to a stirred suspension of NaH (62.3 mg, 80% dispersion by wt in mineral oil, 2.08 mmol) in DME (10 mL) and the mixture was heated at 60° C. under N2 for 30 min. A solution of N-[(1,4-dichloro-7-isoquinolinyl)sulphonyl]-N-(3-pyridylmethyl)glycine t-butyl ester (400 mg, 0.83 mmol) in DME (10 mL) was added and the mixture heated at 80° C. for 4 h. The solvents were evaporated in vacuo, the residue was dissolved with EtOAc (200 mL), and washed with aqueous NH4Cl (200 mL), dried (MgSO4) and evaporated in vacuo. The residue was purified by column chromatography upon silica gel using (i) pentane-EtOAc (70:30 to 50:50) and then (ii) CH2Cl2 -MeOH-0.880NH3 (95:5:0.5 to 90:101) as eluant to give N-[(4-chloro-1-guanidino-7-isoquinolinyl)sulphonyl]-N-(3-pyridylmethyl)glycine t-butyl ester (104 mg, 0.21 mmol) as a pale yellow solid.
