A solution of 6-hydroxy-3,4-dihydro-1H-quinolin-2-one (2.93 g, 17.9 mmol) in DMF (20 mL) is treated with K2CO3 (4.97 g) and BnBr (4.61 g, 26.9 mmol). The suspension is stirred at room temperature for 4 hours and quenched with water (100 mL). The mixture is extracted with EtOAc (50 mL×2) and the combined organics are dried (Na2SO4), concentrated, and purified on silica gel chromatography column with 30-60% EtOAc/Hexanes to yield the title compound (4.40 g, 97%).
