Procedure

To a mixture of methyl 5-((5-(2-(3,4-dichlorophenyl)propan-2-yl)-1-(4-fluoro-3-methoxyphenyl)-1H-imidazol-2-ylthio)methyl)-2-(3-hydroxypropyl)benzoate (90 mg, 0.15 mmol, 1.0 eq), tert-butyl amino(tert-butoxycarbonylamino)methylenecarbamate (76 mg, 0.29 mmol, 2.0 eq) and triphenylphosphine (59 mg, 0.22 mmol, 1.5 eq) in tetrahydrofuran (0.7 mL) was added diisopropylazodicarboxylate (0.04 mL, 0.22 mmol, 1.5 eq). After stirring for 16 h, the reaction mixture was directly poured onto silica gel and purified (0 to 75% ethyl acetate/hexanes). This product was treated with 1:2 trifluoroacetic acid/dichloromethane (2 mL) at room temperature for 16 h. The reaction mixture was concentrated to provide 77 mg (70%) of methyl 5-((5-(2-(3,4-dichlorophenyl)propan-2-yl)-1-(4-fluoro-3-methoxyphenyl)-1H-imidazol-2-ylthio)methyl)-2-(3-guanidinopropyl)benzoate: MS (EI) m/z 759 [(M-Boc)H+].
