Procedure

To a solution of 2-(6-tert-butyl-8-fluoro-1-oxophthalazin-2(1H)-yl)-6-(5-(5-(1-isopropylpiperidin-4-yl)pyridin-2-ylamino)-1-methyl-6-oxo-1,6-dihydropyridazin-3-yl)benzyl acetate (248 mg, 357 μmol, Eq: 1.00) in THF (5.0 ml) was added NaOH (4.29 ml, 4.29 mmol, Eq: 12.0). The reaction mixture heated at 60° C. for 18 h. The solution was cooled to room temperature, and then diluted with saturated NaHCO3 and DCM. The layers were separated. The aqueous layer was extracted three times with DCM. The organic layers were combined, and then dried over Na2SO4. Concentrated in vacuo. The solid was triturated with Et2O and dried under vacuum to give 6-tert-butyl-8-fluoro-2-{2-hydroxymethyl-3-[5-(1′-isopropyl-1′,2′,3′,4′,5′,6′-hexahydro-[3,4′]bipyridinyl-6-ylamino)-1-methyl-6-oxo-1,6-dihydro-pyridazin-3-yl]-phenyl}-2H-phthalazin-1-one (202 mg, 87%).
