Versuchsvorschrift

N-[(4-Chloro-1-guanidino-7-isoquinolinyl)sulphonyl]-N-(3-methoxybenzyl)glycine ##STR22## Guanidine hydrochloride (149 mg, 1.55 mmol) was added in one portion to a suspension of NaH (35 mg, 80% dispersion by wt in mineral oil, 1.16 mmol) in DME (10 mL) and the mixture was heated at 60° C. under N2 for 30 min. N-[(1,4-Dichloro-7-isoquinolinyl)sulphonyl]-N-(3-methoxybenzyl)glycine t-butyl ester (200 mg, 0.39 mmol) was added and the mixture heated at 90° C. for 2 h. The cooled mixture was poured into water, extracted with EtOAc (×3), and the combined organic extracts were washed with brine, dried (Na2SO4) and evaporated in vacuo. The residue was dissolved in Et2O-EtOAc and a solution of HCl in Et2O (0.5 M) was added to give a precipitate. The solid was collected by filtration, triturated with EtOAc and then dried to give N-[(4-chloro-1-guanidino-7-isoquinolinyl)sulphonyl]-N-(3-methoxybenzyl)glycine t-butyl ester hydrochloride (124 mg, 0.21 mmol) as a white solid.
