Reaction Steps

To an appropriate sized vial the trifluoroacetic acid salt of (R)-4-((R)-1-((3-cyclopropyl-6-(3-methoxy-4-(piperazin-1-yl)phenyl)-3H-imidazo[4,5-c]pyridin-4-yl)oxy)ethyl)pyrrolidin-2-one: 3.51 (80 mg, 0.085 mmol) and triethylamine (52 mg, 0.51 mmol) were dissolved in DCM (4 mL). To this mixture acetic anhydride (10.5 mg, 0.1 mmol) was added and the mixture was stirred at room temperature for 30 min. After reaction was complete the solution was concentrated under reduced pressure and the residue was purified via prep HPLC (2-65% acetonitrile in water, 0.1% trifluoroacteic acid buffer) to provide (R)-4-((R)-1-((6-(4-(4-acetylpiperazin-1-yl)-3-methoxyphenyl)-3-cyclopropyl-3H-imidazo[4,5-c]pyridin-4-yl)oxy)ethyl)pyrrolidin-2-one: 3.52 as its trifluoroacetic acid salt.
