Reaction Steps

Methanesulfonic anhydride (9.3 mg, 0.05 mmol) was added to a solution of (R)-4-((R)-1-(6-(4-(piperazin-1-yl)phenyl)pyrazolo[1,5-a]pyrazin-4-yloxy)ethyl)pyrrolidin-2-one 2,2,2-trifluoroacetate 5.44 (22.38 mg, 0.04 mmol) and triethylamine (0.05 mL, 0.36 mmol) in dichloromethane (1.8 mL). After two hours, reaction mixture was loaded directly onto silica gel and purified (0-8% methanol/dichloromethane) to yield (R)-4-((R)-1-((6-(4-(4-(methylsulfonyl)piperazin-1-yl)phenyl)pyrazolo[1,5-a]pyrazin-4-yl)oxy)ethyl)pyrrolidin-2-one 5.46 (19.2 mg).
