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)-4-methylene-pyrrolidine-1-carboxylic acid tert-butyl ester (64 mg, 0.0816 mmol) was dissolved in DCM (1 mL) and HCl (4N dioxane, 1 mL) was added. After 20 minutes all volatiles were removed in vacuo. The crude material was dissolved in DMF (1 mL) and Methoxycarbonylamino-pyridin-3-yl-acetic acid/NaCl (1:1, 22 mg, 0.0816 mmol), HATU (31 mg, 0.0816 mmol), and DIEA (31.5 mg, 0.245 mmol) were added and stirring at room temperature was continued. After 30 minutes, aqueous HCl (1N, 0.1 mL) was added and the reaction mixture was purified via RP-HPLC (eluent: water/MeCN w/ 0.1% TFA). The product containing fractions were lyophilized to yield the product (8.9 mg).
