Procedure

To a solution of 2-(4-((5-(2-(4-chloro-3-methoxyphenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazol-2-ylthio)methyl)-3,5-difluorophenoxy)ethanol (153 mg, 0.27 mmol) in THF (0.39 mL) were added PPh3 (107 mg, 0.41 mmol), 1,3-bis(tert-butoxycarbonyl)guanidine (144 mg, 0.55 mmol) and DIAD (85 μL, 0.41 mmol). After stirring overnight, the reaction mixture was diluted with EtOAc, washed with H2O and brine, dried over Na2SO4 and concentrated. The crude material was purified by flash chromatography (80% EtOAc/hexanes) to afford tert-butyl(tert-butoxycarbonylamino)(2-(4-((5-(2-(4-chloro-3-methoxyphenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazol-2-ylthio)methyl)-3,5-difluorophenoxy)ethylamino)methylenecarbamate (279 mg), which was taken to the final step without further purification. MS (EI) m/z 804.5 (MH+).
