Procedure

This compound was prepared using the procedure used to prepare [1-(6-{5-[6-(4-{2-[2-(2-Methoxycarbonylamino-3-methyl-butyryl)-2-aza-bicyclo[2.2.1]hept-3-yl]-3H-imidazol-4-yl]-phenyl)-naphthalen-2-yl]-1H-imidazol-2-yl]-5-aza-spiro[2.4]heptane-5-carbonyl)-2-methyl-propyl]-carbamic acid methyl ester (example EZ) using [2-Methyl-1-(3-{5-[6-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-naphthalen-2-yl]-1H-imidazol-2-yl]-2-aza-bicyclo[2.2.1]heptane-2-carbonyl)-propyl]-carbamic acid methyl ester (2.25 mmol), 645-(4-Bromo-phenyl)-1H-imidazol-2-yl]-5-aza-spiro[2.4]heptane-5-carboxylic acid tert-butyl ester (2.39 mmol), and potassium carbonate (2M, 4.3 mL, 8.55 mmol). The reaction was performed under an argon atmosphere. The crude reaction was diluted in ethyl acetate, washed with water and purified by normal phase silica chromatography (50-100% Hexanes:EthylAcetate+10% Methanol). 6-{5-[4-(6-{2-[2-(2-Methoxycarbonylamino-3-methyl-butyryl)-2-aza-bicyclo[2.2.1]hept-3-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 (1.05 g, 60%) was obtained as a tan solid.
