(S)-tert-butyl 2-(5-(4-(2-((1R,3S,4S)-2-((S)-2-(methoxycarbonylamino)-3-methylbutanoyl)-2-azabicyclo[2.2.1]heptan-3-yl)-1H-naphtho[1,2-d]imidazol-7-yl)phenyl)-1H-imidazol-2-yl)pyrrolidine-1-carboxylate (73 mg, 0.10 mmol) in DCM (3 mL) and MeOH (3 mL) was added HCl (4M in dioxane, 0.5 mL). The solution stirred for 3 h at 35° C., after which the solvent was removed. The intermediate (31 mg, 0.13 mmol) was dissolved in DMF (1 mL). (S)-2-(methoxycarbonylamino)-2-(tetrahydro-2H-pyran-4-yl)acetic acid (16 mg, 0.05 mmol), HATU (19 mg, 0.05 mmol), and DIPEA (0.04 mL, 0.25 mmol) were added sequentially. The solution stirred o/n and the mixture was purified by HPLC to yield product (27.6 mg). LCMS-ESI+: calc'd for C46H54N8O7: 830.97 (M+); Found: 832.56 (M+H+).
