Reaction Steps

To (1R,3S,4S)-tert-butyl 3-(7-(4-(2-((S)-1-((S)-2-(methoxycarbonylamino)-3-methylbutanoyl) pyrrolidin-2-yl)-1H-imidazol-5-yl)phenyl)-1H-naphtho[1,2-d]imidazol-2-yl)-2-azabicyclo[2.2.1]heptane-2-carboxylate (280 mg, 0.38 mmol) in DCM (5 mL) was added HCl (4M in dioxane, 1 mL). The solution stirred for 2 h, and the solvent was removed. The intermediate (80 mg, 0.13 mmol) was dissolved in DMF (2 mL). (2S,3R)-3-methoxy-2-(methoxycarbonylamino)butanoic acid (24 mg, 0.13 mmol), HATU (48 mg, 0.13 mmol), and DIPEA (0.11 mL, 0.64 mmol) were added sequentially. The solution stirred o/n and the mixture was purified by HPLC to yield product (54.6 mg). LCMS-ESI+: calc'd for C44H52N8O7: 804.93 (M+); Found: 806.23 (M+H+).
