Reaction Steps

N-(4-(3-(5-tert-Butylisoxazol-3-yl)ureido)phenyl)-5-(pyrrolidin-3-yloxy)picolinamide hydrochloride (150 mg, 0.30 mmol) was suspended in 3 mL of THF at rt. Methylsulfonylethene (29 μL, 0.33 mmol) and TEA (126 μL, 0.90 mmol) were added sequentially. The resulting mixture was heated at 60° C. for 1 h, then heated at 52° C. for 60 h. LC-MS indicated the reaction was complete. The organic solvent was evaporated under reduced pressure and the residue was purified by reverse phase HPLC to give N-(4-(3-(5-tert-butylisoxazol-3-yl)ureido)phenyl)-5-(1-(2-(methylsulfonyl)ethyl)pyrrolidin-3-yloxy)picolinamide (136 mg, 79%). LC-MS (ESI) m/z 571 (M+H)+.
