Reaction Steps

Title compound was prepared according to the method employed to prepare (S)-1-((S)-8-(5-(4-(6-(2-((S)-1-((R)-2-(methoxycarbonylamino)-2-phenylacetyl)pyrrolidin-2-yl)-1H-imidazol-5-yl)naphthalen-2-yl)phenyl)-1H-imidazol-2-yl)-1,4-dioxa-7-azaspiro[4.4]nonan-7-yl)-3-methyl-1-oxobutan-2-ylcarbamic acid methyl ester, except that methyl (S)-3-methyl-1-oxo-1-((S)-8-(5-(6-(4-(2-((S)-pyrrolidin-2-yl)-1H-imidazol-5-yl)phenyl)naphthalen-2-yl)-1H-imidazol-2-yl)-1,4-dioxa-7-azaspiro[4.4]nonan-7-yl)butan-2-ylcarbamate 3× HCl salt was used instead of methyl (S)-3-methyl-1-oxo-1-((S)-8-(5-(4-(6-(2-((S)-pyrrolidin-2-yl)-1H-imidazol-5-yl)naphthalen-2-yl)phenyl)-1H-imidazol-2-yl)-1,4-dioxa-7-azaspiro[4.4]nonan-7-yl)butan-2-ylcarbamate 3× HCl salt.
