Reaction Steps

A solution of (R)-tert-butyl 4-((3-carbamoyl-6-(5-(methylthio)-1,3,4-oxadiazol-2-yl)pyrrolo[1,2-b]pyridazin-4-yl)amino)-3,3-dimethylpiperidine-1-carboxylate (306 mg, 0.610 mmol) and mCPBA (265 mg, 1.182 mmol) in chloroform (6 mL) was stirred at room temperature for 2 h. Additional mCPBA (78 mg) was added. After one more hour at room temperature, the staring material was consumed. The crude solution was taken to the next reaction without purification. MS (ES+) m/z: 518.3 (M+H).
