Versuchsvorschrift

(2S,4S)-benzyl 2-(5-(4′-(2-(tert-butoxycarbonylamino)acetyl)biphenyl-4-yl)-1H-imidazol-2-yl)-4-(methoxymethyl)pyrrolidine-1-carboxylate (640 mg, 1.02 mmol) was dissolved in DCM (8 mL), MeOH (2 mL) and HCl (4 M in dioxane, 2 mL) was added. The reaction mixture was stirred for 14 h and then concentrated under reduced pressure. The crude residue was treated with (2S,4S)-1-((S)-2-(methoxycarbonylamino)-3-methylbutanoyl)-4-(methylthio)pyrrolidine-2-carboxylic acid (324 mg, 1.02 mmol), HATU (388 mg, 1.02 mmol) and DMF (10 mL), then DIPEA (0.9 mL, 5.12 mmol) was added dropwise. After 1 h, the mixture was diluted with EtOAc and washed successively with saturated aqueous NaHCO3 and brine. The organics were dried over MgSO4, filtered and concentrated under reduced pressure. The crude residue was purified by silica column chromatography (0% to 30% MeOH/EtOAc) to afford (2S,4S)-benzyl 2-(5-(4′-(2-((2S,4S)-1-((S)-2-(methoxycarbonylamino)-3-methylbutanoyl)-4-(methylthio)pyrrolidine-2-carboxamido)acetyl)biphenyl-4-yl)-1H-imidazol-2-yl)-4-(methoxymethyl)pyrrolidine-1-carboxylate (487 mg, 58%).
