Reaction Steps

A mixture of (S)-tert-butyl 2-(5-(6-(2-((S)-1-(tert-butoxycarbonyl)pyrrolidin-2-yl)-1H-benzo[d]imidazol-6-yl)naphthalen-2-yl)-1H-imidazol-2-yl)pyrrolidine-1-carboxylate and (S)-tert-butyl 2-(5-(7-(2-((S)-1-(tert-butoxycarbonyl)pyrrolidin-2-yl)-1H-benzo[d]imidazol-6-yl)naphthalen-2-yl)-1H-imidazol-2-yl)pyrrolidine-1-carboxylate as TFA salts (74 mg) and TFA (2 mL) in CH2Cl2 (10 mL) was stirred at ambient conditions for 4 hours. The volatile component was removed in vacuo. The crude material was purified by a reverse phase HPLC (0 to 50% water/acetonitrile/TFA) to provide a TFA salt of 2-((S)-pyrrolidin-2-yl)-6-(6-(2-((S)-pyrrolidin-2-yl)-1H-imidazol-5-yl)naphthalen-2-yl)-1H-benzo[d]imidazole (32 mg, 31%) as yellow oil and a TFA salt of 2-((S)-pyrrolidin-2-yl)-6-(7-(2-((S)-pyrrolidin-2-yl)-1H-imidazol-4-yl)naphthalen-2-yl)-1H-benzo[d]imidazole (16 mg) as yellow oil.
