Participants

Reaction Steps

To a solution of 4-chloro-N-{[4-chloro-3-({3-cyano-5-[(dimethylamino)methyl]phenyl}oxy)-2-fluorophenyl]methyl}-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-5-carboxamide (82 mg, 0.138 mmol) in DCM (6.0 ml) was added TFA (2.00 mL) and the reaction mixture was stirred ar RT for one hour. The solvent was removed and the crude material was purified via reverse phase HPLC to give 4-chloro-N-{[4-chloro-3-({3-cyano-5-[(dimethylamino)methyl]phenyl}oxy)-2-fluorophenyl]methyl}-1H-imidazole-5-carboxamide trifluoroacetate (29 mg, 0.050 mmol, 36% yield). 1H NMR (400 MHz, METHANOL-d4) δ ppm 7.72 (s, 1H), 7.62 (s, 1H), 7.27-7.49 (m, 4H), 4.63 (s, 2H), 4.35 (s, 2H), 2.85 (s, 6H). LC-MS (ES+) m/z 462.08, [M+H].
