Procedure
The title compound was prepared according to the method employed to prepare (S)-benzyl 1-((S)-2-(methoxycarbonylamino)-3-methylbutanoyl)-4-oxopyrrolidine-2-carboxylate, except that methyl (S)-2-((S)-2-(6-(9,9-difluoro-7-(2-((S)-pyrrolidin-2-yl)-1H-imidazol-5-yl)-9H-fluoren-2-yl)-1H-benzo[d]imidazol-2-yl)pyrrolidin-1-yl)-2-oxo-1-(tetrahydro-2H-pyran-4-yl)ethylcarbamate 3HCl salt was used instead of (S)-benzyl 4-oxopyrrolidine-2-carboxylate hydrochloride. MS (ESI) m/z 879.88 [M+H]+. (122 mg, 52%).
