Procedure

5-Bromo-6-methylquinolin-2(1H)-one (103.5 mg, 0.435 mmol) was suspended into DMF (3 mL). To the suspension, was added NaH (17.4 mg 60% in mineral oil) at room temperature. After 2 h stirring, CF3CH2OTf (201.8 mg, 0.869 mmol) was added into the mixture at room temperature. The reaction mixture was stirred for 2 h at the same temperature. The reaction mixture was quenched with water (30 mL). The whole was extracted with AcOEt (30 mL×3). Organic layer was washed with brine (30 mL) and dried over Na2SO4. The solvent was removed under a reduced pressure to give the crude product. Gilson PHPLC purification gave 5-bromo-6-methyl-1-(2,2,2-trifluoroethyl)quinolin-2(1H)-one.
