Versuchsvorschrift

To 2-(6-tert-butyl-8-fluoro-1-oxophthalazin-2(1H)-yl)-6-(5-(5-(4-isopropylpiperazin-1-yl)pyridin-2-ylamino)-1-methyl-6-oxo-1,6-dihydropyridazin-3-yl)benzyl acetate (153 mg, 220 μmol, Eq: 1.00) in THF (2.0 ml) was added an aqueous solution of 1N NaOH (2.0 mL, 2.00 mmol, Eq: 9.08). The resulting solution heated at 60° C. for 2 h. The mixture was cooled to room temperature. The solution was diluted with saturated NaHCO3 and DCM. The layers were separated. The aqueous layer was extracted three times with DCM. The combined organics were dried over MgSO4. The solution was filtered. Concentrated in vacuo. The crude material was purified by flash chromatography (silica gel, 12 g, 0% to 50% (60:10:1 DCM:MeOH:NH4OH)/DCM gradient) to give a cream solid. The solid was triturated with Et2O. The solid was filtered, then dissolved in 2 ml DCM. A solution of 1.0 M HCl in Et2O (2 ml) was added. A solid formed. The solid was filtered and dried under vacuum to give 6-tert-butyl-8-fluoro-2-(2-hydroxymethyl-3-{5-[5-(4-isopropyl-piperazin-1-yl)-pyridin-2-ylamino]-1-methyl-6-oxo-1,6-dihydro-pyridazin-3-yl}-phenyl)-2H-phthalazin-1-one HCl (57.5 mg, 38%).
