실험 절차

To a solution of 4-chloro-N-[(4-chloro-3-{[3-cyano-5-(trifluoromethyl)phenyl]oxy}-2-fluorophenyl)methyl]-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-5-carboxamide (97 mg, 0.161 mmol) in DCM (7 ml) was added TFA (3 ml) and the reaction mixture was stirred at rt for 2 hours. The reaction mixture was quenched with saturated sodium bicarbonate and the organic layer was separated. The solvent was removed and the crude material was purified via silica gel chromatography to give 4-chloro-N-[(4-chloro-3-{[3-cyano-5-(trifluoromethyl)phenyl]oxy}-2-fluorophenyl)methyl]-1H-imidazole-5-carboxamide (45 mg, 0.095 mmol, 59% yield). 1H NMR (400 MHz, METHANOL-d4) δ ppm 7.82 (s, 1H), 7.69 (s, 1H), 7.47-7.53 (m, 2H), 7.35-7.42 (m, 2H), 4.63 (s, 2H). LC-MS (ES+) m/z 473.07, [M+H].
