Procedure

To a solution of 3-(4-((5-(2-(4-chloro-3-methoxyphenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazol-2-ylthio)methyl)-3,5-difluorophenyl)propan-1-ol (407 mg, 0.73 mmol) in anhyd THF (0.97 mL) were added PPh3 (285 mg, 1.08 mmol), 1,3-bis(tert-butoxycarbonyl)guanidine (384 mg, 1.45 mmol) and diisopropyl azodicarboxylate (DIAD) (225 μL, 1.08 mmol) sequentially. 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 yield tert-butyl(tert-butoxycarbonylamino)(3-(4-((5-(2-(4-chloro-3-methoxyphenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazol-2-ylthio)methyl)-3,5-difluorophenyl)propylamino)methylenecarbamate (740 mg), which was taken to the next step without further purification. MS (EI) m/z 802.50 (MH+).
