Versuchsvorschrift

A solution of (4-bromo-7-(4-methoxyphenyl)isoquinolin-1-yl)guanidine (38 mg, 0.1 mmol) in industrial methylated spirits (2.0 mL) containing 5% Pd-C (10 mg) was stirred under an atmosphere of H2 (3.5 atmospheres) at 23° C. for 3 days. The mixture was filtered through Arbocel™ with ethanol rinsing, the filtrate was evaporated in vacuo and the residue was purified by column chromatography on silica gel using dichloromethane:methanol:0.88 ammonia (97:3:0.3) as eluant to give (7-(4-methoxyphenyl)isoquinolin-1-yl)guanidine (24 mg, 0.08 mmol) as a white solid.
