Reaction Steps

Imidazole (0.28 g, 4.16 mmol) and tert-butylchlorodimethylsilane (0.574 g, 3.81 mmol) were added to a solution of 3-(4-(3-((4-(difluoromethyl)pyrimidin-2-yl)amino)-5-methylphenyl)-1H-pyrazol-1-yl)propane-1,2-diol (1.3 g, 3.46 mmol) in DMF (12 mL) at 0° C. The mixture was stirred at 0° C. for 90 minutes. The mixture was allowed to warm to room temperature, diluted with EtOAc, and washed with water. The organic layer was dried over anhydrous magnesium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (0-100% EtOAc/Hexane) to afford 1-((tert-butyldimethylsilyl)oxy)-3-(4-(3-((4-(difluoromethyl)pyrimidin-2-yl)amino)-5-methylphenyl)-1H-pyrazol-1-yl)propan-2-ol. MS ESI calc'd. for C24H34F2N5O2Si [M+H]+ 490. found 490.
