A solution of tert-butyl 3-chloro-4-((5-(2-(4-chloro-3-methoxyphenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazol-2-ylthio)methyl)-5-fluorophenylcarbamate (200 mg) in DCM (1 mL) was treated with TFA (1 mL) with stirring. After 1 h, the solution was concentrated under reduced pressure, diluted with DCE (5 mL). The organic layer was washed with water, satd NaHCO3 and brine, then dried (MgSO4) and concentrated to afford the title compound (152 mg, 90%). 1H NMR (400 MHz, MeOD) δ 7.40 (s, 1H), 7.36 (d, J=9.1 Hz, 1H), 6.93 (d, J=8.4, 1H), 6.87 (d, J=8.4 Hz, 1H), 6.68-6.61 (m, 2H), 6.53 (s, 1H), 6.40-6.27 (m, 3H), 4.01 (s, 2H), 3.76 (s, 3H), 1.58 (s, 6H); MS (EI) m/z 534 (MH+).
