Reaction Steps

S)-Methyl 1-(4-(3-(2-chloro-5-fluoro-3-(methanesulfonamido)phenyl)-1-isopropyl-1H-pyrazol-4-yl)pyrimidin-2-ylamino)propan-2-ylcarbamate. A mixture of the aniline product of step 1 (46 mg), pyridine (2 ml), triethylamine (1 mL), DCM (4 ml), and methanesulfonyl chloride (23 ul, 0.3 mmol) was stirred at rt for 16 h. The crude reaction mixture was concentrated, then the residue was taken up in a mixture of toluene (9 ml), ethanol (1 ml), sodium carbonate (2 g), and water (10 ml). The stirred mixture was heated at 85° C. for 16 h. Workup as for Step 1 provided the crude product, which was purified by silica gel chromatography (60:1 to 40:1 DCM/methanol eluant) to provide the title compound.
