To a stirring solution of 5-bromo-1-(2-hydroxyethyl)pyridin-2(1H)-one (3000 mg, 13.7 mmol) in DMF (25 mL) was added sodium hydride (60% dispersion in mineral oil, 632.6 mg, 27.5 μmol) portionwise. After stirred for 30 min at 23° C., additional DMF (20 mL) was added to the thick suspension. To this was added 4-chloro-7-methoxyquinoline (2664 mg, 13.7 mmol). Upon completion, the reaction was quenched with 5% NaHCO3 (100 mL), and the aqueous was extracted with CH2Cl2 (4×75 mL). The combined organics were dried over MgSO4, concentrated from toluene, and purified on 80 grams of silica eluting with 30-80% of 5% MeOH/CH2Cl2. The product was isolated as a white solid. MS (ESI pos. ion) m/z (MH+): 375/377.
