Reaction Steps

To the TFA salt of (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: (45 mg, 0.1 mmol) in DCM (1 mL) and TEA (0.07 mL, 0.5 mmol) was added acetic anhydride (0.014 mL, 0.15 mmol). The reaction was stirred at rt for 2 h. The mixture was then concentrated and purified by prep-HPLC (MeCN:water gradient; TFA modified) to give (R)-4-((R)-1-((5-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-1-cyclopropyl-1H-benzo[d]imidazol-7-yl)oxy)ethyl)pyrrolidin-2-one: 3.59 as a TFA salt. The salt was then converted to the free base by treatment with MP carbonate resin.
