To a stirring solution of methyl 2-(2-oxo-6-(trifluoromethoxy)quinolin-1(2H)-yl)acetate (1.2 mmol) in THF/water (2:1) was added LiOH. H2O (8.1 mmol). The resulting mixture was stirred overnight. The crude product mixture was slowly acidified with 1N HCl solution and then extracted with EtOAc. The organic phase was separated, dried (MgSO4), filtered and concentrated under vacuum to give 2-(2-oxo-6-(trifluoromethoxy)quinolin-1(2H)-yl)acetic acid. Retention time (min)=1.783, method [1], MS(ESI) 288.1 (M+H).
