Reaction Steps

tert-butyl 4-(6-(1-cyclopropyl-7-((R)-1-((R)-1-((R)-1-(4-methoxyphenyl)ethyl)-5-oxopyrrolidin-3-yl)ethoxy)-1H-benzo[d]imidazol-5-yl)pyridin-3-yl)piperazine-1-carboxylate (129 mg, 0.189 mmol) was treated with TFA (3 mL) at 60° C. for 14 h. The reaction mixture was then concentrated to give (R)-4-((R)-1-((1-cyclopropyl-5-(5-(piperazin-1-yl)pyridin-2-yl)-1H-benzo[d]imidazol-7-yl)oxy)ethyl)pyrrolidin-2-one: 3.58 as a TFA salt which was used further without purification. LCMS-ESI+ (m/z): [M+H]+ calcd for C25H31N6O2: 447.3; found 447.2.
