الإجراء التجريبي

To a mixture of 7-tert-Butyl-3-(2-methyl-3-{1-methyl-5-[5-(morpholine-4-carbonyl)-pyridin-2-ylamino]-6-oxo-1,6-dihydro-pyridazin-3-yl}-phenyl)-3H-quinazolin-4-one (11 mg, 0.018 mmol) and sodium cyanoborohydride (1.3 mg, 0.019 mmol) in 1 mL methanol was added 1 drop of 2M hydrochloric acid in methanol to bring the pH to 3. After stirring for 45 minutes, the resulting mixture was partitioned between ethylacetate and dilute aqueous NaHCO3. The ethylacetate layer was washed with brine, dried over anhydrous MgSO4, concentrated in vacuo, and purified by preparative TLC (5% MeOH/CH2Cl2) to yield 7-tert-Butyl-3-(2-methyl-3-{1-methyl-5-[5-(morpholine-4-carbonyl)-pyridin-2-ylamino]-6-oxo-1,6-dihydro-pyridazin-3-yl}-phenyl)-2,3-dihydro-1H-quinazolin-4-one (6.5 mg, 0.011 mmol). MS (ESI) 608 (M+H)+.
