Reaction Steps

[1-(2-{5-[6-(4-{2-[4-Ethoxy-1-(2-methoxycarbonylamino-2-phenyl-acetyl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-phenyl)-naphthalen-2-yl]-1H-imidazol-2-yl}-pyrrolidine-1-carbonyl)-2-methyl-propyl]-carbamic acid methyl ester was prepared following the procedure for [1-(2-{5-[6-(4-{2-[1-(2-Methoxycarbonylamino-2-phenyl-propionyl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-phenyl)-naphthalen-2-yl]-1H-imidazol-2-yl}-pyrrolidine-1-carbonyl)-2-methyl-propyl]-carbamic acid methyl ester, substituting 4-Ethoxy-pyrrolidine-1,2-dicarboxylic acid 1-tert-butyl ester for Pyrrolidine-1,2-dicarboxylic acid 1-tert-butyl ester and Methoxycarbonylamino-phenyl-acetic acid for 2-Methoxycarbonylamino-2-phenyl-propionic acid. LCMS-ESI+: calc'd for C49H54N8O7: 866.41 (M+); Found: 867.35 (M+H+).
