実験手順
To a solution of tert-butyl 2-(8-(trifluoromethyl)quinolin-5-yl)acetate (400 mg, 1.28 mmol) in DCM (5 mL) was added TFA (10 mL) dropwise. The reaction was stirred at room temperature overnight. After the reaction was complete, the solvent was removed and the residue was purified (silica gel chromatography) to give the final product 2-(8-(trifluoromethyl)quinolin-5-yl)acetic acid (180 mg, 54%). LC-MS (0.05% TFA): [M+1]+ 256.1. 1H-NMR (DMSO-d6, 400 MHz): δ 12.70 (s, 1H), 9.07(m, 1H), 8.56 (m, 1H), 8.15 (d, 1H), 7.74(m,1H), 7.68 (m,1H), 4.23(s, 2H). 13C-NMR (DMSO-d6, 100MHz): 67 171.9, 151.0, 144.0, 138.3, 133.5, 127.87, 127.83, 127.78, 125.3, 123.1, 122.2, 37.7.
