Reaction Steps

To (S)-tert-butyl 2-(5-(2-(2-((S)-1-((S)-2-(methoxycarbonylamino)-3-methylbutanoyl)pyrrolidin-2-yl)-1H-naphtho[1,2-d]imidazol-7-yl)benzo[b]thiophen-6-yl)-1H-imidazol-2-yl)pyrrolidine-1-carboxylate (53 mg, 0.07 mmol) in DCM (3 mL) was added HCl (4M in dioxane, 0.25 mL). The solution stirred for 1 h, and the solvent was removed. The intermediate was dissolved in DMF (2 mL). (R)-2-(methoxycarbonylamino)-2-phenylacetic acid (15 mg, 0.07 mmol), COMU (36 mg, 0.08 mmol), and DIPEA (0.06 mL, 0.35 mmol) were added sequentially. The solution was stirred o/n and the mixture was purified by HPLC to yield product (14.8 mg). LCMS-ESI+: calc'd for C47H48N8O6S: 853.00 (M+); Found: 853.22 (M+H+).
