Versuchsvorschrift

To 30 mg (0.06 mmol) 7-[2-(4-benzyloxy-6-oxo-6H-pyridazin-1-yl)-ethyl]-3,4-dihydro-1H-isoquinoline-2-carboxylic acid tert-butyl ester (example 25.1a) in 2.0 mL DCM is added 50 μL trifluoroacetic acid at RT. The solvent is evaporated and the residue is purified via reverse HPLC chromatography (Waters SunFire, C18; water (0.1% formic acid)/acetonitrile (0.1% formic acid) 95:5 to 10:90).
