Reaction Steps

The title compound was prepared according to the method employed to prepare (S)-Tert-butyl 2-(7-(4-(2-((S)-7-((S)-2-(methoxycarbonylamino)-3-methylbutanoyl)-1,4-dioxa-7-azaspiro[4.4]nonan-8-yl)-1H-imidazol-5-yl)phenyl)-1H-naphtho[1,2-d]imidazol-2-yl)pyrrolidine-1-carboxylate, except that, respectively, methyl (S)-1-((S)-2-(5-(6-bromonaphthalen-2-yl)-1H-imidazol-2-yl)pyrrolidin-1-yl)-3-methyl-1-oxobutan-2-ylcarbamate and (R)-tert-butyl 4-(5-(4-bromophenyl)-1H-imidazol-2-yl)oxazolidine-3-carboxylate were used instead of methyl (S)-1-((S)-8-(5-(4-bromophenyl)-1H-imidazol-2-yl)-1,4-dioxa-7-azaspiro[4.4]nonan-7-yl)-3-methyl-1-oxobutan-2-ylcarbamate (100 mg, 0.197 mmol), bis(pinacolato)diboron and (S)-tert-butyl 2-(7-bromo-1H-naphtho[1,2-d]imidazol-2-yl)pyrrolidine-1-carboxylate.
