Reaction Steps

In a 20 mL sealed tube, was dissolved 8-(4-(4-(4-chlorophenyl)phthalazin-1-ylamino)phenoxy)-1,5-naphthyridin-2(1H)-one (0.25 g, 0.508 mmol) in THF (2.2 mL), and the mixture was cooled to 0° C. Sodium Hydride, 60% in mineral oil (0.045 g, 1.12 mmol), was added and the mixture was stirred at 0° C. for 1 hour. Iodomethane (0.070 mL, 1.12 mmol), was added and the mixture was warmed to 60° C., and stirred for 3 hours. A mixture of products was revealed by LC/MS. The mixture was cooled to RT, quenched with water, extracted into ethyl acetate, washed 1× water, 1×NaCl, dried with Na2SO4, filtered through flitted funnel, and filtrate was concentrated. The crude concentrate was purified by reverse phase chromatography. The product containing fractions were extracted into DCM, washed 1× sodium carbonate, 1×H2O, dried with Na2SO4, filtered through flitted funnel, and the filtrate was concentrated down to a light yellow solid containing two methylated products. The solids were suspended in methanol, filtered, rinsed with methanol, and air dried to yield 8-(4-((4-(4-chlorophenyl)phthalazin-1-yl)(methyl)amino)phenoxy)-1,5-naphthyridin-2(1H)-one. MS: [M+H]=506.0; Calc'd 505.9 for C29H20ClN5O2.
