Versuchsvorschrift

To 8-(trifluoroacetylamino)isoquinolin-5-ylcarbamic acid phenyl ester (35 mg) were added 2-(3,5-difluorophenoxy)-1-methylethylamine hydrochloride (22 mg) obtained in Example 52 as a synthetic intermediate, dimethyl sulfoxide (1 ml) and N,N-diisopropylethylamine (81 μl), and the mixture was stirred at room temperature for 30 min. The reaction mixture was diluted with ethyl acetate and, after washing with water, the solvent was evaporated. The obtained crude product was purified by reversed-phase high performance liquid chromatography (reversed-phase HPLC) (water-acetonitrile, each containing 0.1% trifluoroacetic acid (TFA)) to give N-[2-(3,5-difluorophenoxy)-1-methylethyl]-N′-[8-(trifluoroacetylamino)isoquinolin-5-yl]urea TFA salt (13.7 mg).
