To a stirring mixture of the above crude 6-(trifluoromethyl)quinolin-2(1H)-one in DMF/THF (0.5 M, 1:1) at rt was added NaH portionwise (1.2 g, 30.88 mmol) over 15 min. The reaction mixture was stirred at rt for additional 20 min before a solution of bromo methyl acetate (4.73 g, 30.88 mmol) in THF was added. The resulting mixture was stirred at rt until the starting material was consumed. The mixture was slowly quenched with brine and extracted with EtOAc. The crude product mixture was purified by column chromatography (3.6 g, 82% in two steps). Retention time (min)=2.042, method [1], MS (ESI) 286.1 (M+H).
