Participants

Reaction Steps

To a solution of N-({3-[(2-amino-5-cyano-4-fluorophenyl)oxy]-4-chloro-2-fluorophenyl}methyl)-4-chloro-1-({[2-(trimethylsilyl)ethyl]oxy}methyl)-1H-imidazole-5-carboxamide (35 mg, 0.062 mmol) in DCM (6 ml) was added TFA (3.0 mL) and the reaction mixture was stirred for 3 hours at RT. The solvent was removed and the crude material was purified via reverse phase HPLC and neutralized to give N-({3-[(2-amino-5-cyano-4-fluorophenyl)oxy]-4-chloro-2-fluorophenyl}methyl)-4-chloro-1H-imidazole-5-carboxamide (9.0 mg, 0.021 mmol, 33% yield). 1H NMR (400 MHz, METHANOL-d4) δ ppm 7.70 (s, 1H), 7.20-7.42 (m, 2H), 6.58 (d, 1H), 6.49 (d, 1H), 4.62 (s, 2H). LC-MS (ES+) m/z 438.13, [M+H].
