実験手順

2-(6-{5-[3-(6-tert-Butyl-8-fluoro-1-oxo-1H-phthalazin-2-yl)-2-hydroxymethyl-phenyl]-1-methyl-2-oxo-1,2-dihydro-pyridin-3-ylamino}-pyridin-3-yl)-2-methyl-propionic acid (50 mg, 0.08 mmol), morpholine (11 mg, 0.12 mmol), EDC (23 mg, 0.12 mmol), and DMAP (15 mg, 0.12 mmol) were dissolved in 1 ml of DCM and stirred at room temperature under nitrogen overnight. Ethyl acetate and saturated aqueous ammonium chloride were added and the layers were separated. The organic layer was washed with dilute ammonium chloride, then saturated aqueous sodium bicarbonate, dried, and concentrated. The crude product was purified by flash chromatography using a gradient of 0% to 10% methanol in DCM to give 40 mg (74%) of 6-tert-butyl-2-(3-{5-[5-(1,1-dimethyl-2-morpholin-4-yl-2-oxo-ethyl)-pyridin-2-ylamino]-1-methyl-6-oxo-1,6-dihydro-pyridin-3-yl}-2-hydroxymethyl-phenyl)-8-fluoro-2H-phthalazin-1-one.
