الإجراء التجريبي

2-Methoxycarbonylamino-3,3-dimethyl-butyric acid (43 mg, 0.227 mmol) EDC-HCl (44 mg, 0.227 mmol) and HOBt (32 mg, 0.237 mmol) were combined in DMF (2 mL) and stirred for 20 min at RT. (1-{6-[5-(6-{4-[2-(4-Cyano-pyrrolidin-2-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 tris-hydrochloride (150 mg, 0.189 mg) was added, the reaction mixture was cooled to 0° C. and NMM (0.104 mL, 0.947 mmol) was added dropwise. After 20, the reaction mixture was warmed to RT. 30 min later, the mixture was diluted with EtOAc and washed with NaHCO3, then brine. The organic phase was dried over MgSO4, then filtered and concentrated. The resulting residue was purified by HPLC to afford the title compound (73 mg, 45%). MS (ESI) m/z 854 [M+H]+.
