Reaction Steps

[1-(2-{5-[6-(4-{2-[5-(2-Methoxycarbonylamino-2-phenyl-acetyl)-5-aza-spiro[2.4]hept-6-yl]-3H-imidazol-4-yl}-phenyl)-naphthalen-2-yl]-1H-imidazol-2-yl}-pyrrolidine-1-carbonyl)-2-methyl-propyl]-carbamic acid methyl ester (0.08 g, 28%) was prepared following the procedure for {2-[4,4-Difluoro-2-(5-{4-[6-(2-{1-[2-methoxycarbonylamino-2-(tetrahydro-pyran-4-yl)-acetyl]-pyrrolidin-2-yl}-3H-imidazol-4-yl)-naphthalen-2-yl]-phenyl}-1H-imidazol-2-yl)-pyrrolidin-1-yl]-2-oxo-1-phenyl-ethyl}-carbamic acid methyl ester, substituting 2-Methoxycarbonylamino-3-methyl-butyric acid for Methoxycarbonylamino-(tetrahydro-pyran-4-yl)-acetic acid and 6-[5-(4-{6-[2-(1-Benzyloxycarbonyl-pyrrolidin-2-yl)-3H-imidazol-4-yl]-naphthalen-2-yl}-phenyl)-1H-imidazol-2-yl]-5-aza-spiro[2.4]heptane-5-carboxylic acid tert-butyl ester for 2-[5-(4-{6-[2-(1-Benzyloxycarbonyl-pyrrolidin-2-yl)-3H-imidazol-4-yl]-naphthalen-2-yl}-phenyl)-1H-imidazol-2-yl]-4,4-difluoro-pyrrolidine-1-carboxylic acid tert-butyl ester. LCMS-ESI+: calc'd for C49H52N8O6: 848.40 (M+); Found: 849.95 (M+H+).
