A solution of N-methyl-N-[1-(4-{1-oxo-6-[(S)-1-(tetrahydrofuran-2-yl)methoxy]-1H-isoquinolin-2-yl}-phenyl)-piperidin-3-yl]-acetamide (552 mg) was stirred in 20% sulfuric acid (with methanol as solubilizing agent) for 16 h at 90° C. The mixture was neutralized with 2N NaOH, extracted with dichloromethane, dried over magnesium sulfate and concentrated. The residue was purified by preparative HPLC. In this way the product was obtained with molecular weight 433.56 (C26H31N3O3); MS (ESI): 434 (M+H+).
