Potassium Carbonate → racemic 5-{[4-(3-{[4-(difluoromethyl)pyrimidin-2-yl]amino}-5-methylphenyl)-1H-pyrazol-1-yl]methyl}-4-(hydroxymethyl)-1,3-oxazolidin-2-one

Reaction Steps

A solution of (5-{[4-(3-{[4-(difluoromethyl)pyrimidin-2-yl]amino}-5-methylphenyl)-1H-pyrazol-1-yl]methyl}-2-oxo-1,3-oxazolidin-4-yl)methyl trifluoroacetate (80 mg, 0.15 mmol) and potassium carbonate (80 mg, 0.58 mmol) in methanol (3 mL) was stirred at 25° C. for 30 minutes. The reaction mixture was diluted with water and extracted with ethyl acetate. The organic layer was dried over sodium sulfate, filtered, and concentrated under reduced pressure to afford the crude product residue. The crude product residue was purified by prep-TLC (ethyl acetate) to give racemic 5-{[4-(3-{[4-(difluoromethyl)pyrimidin-2-yl]amino}-5-methylphenyl)-1H-pyrazol-1-yl]methyl}-4-(hydroxymethyl)-1,3-oxazolidin-2-one. MS ESI calc'd. for C20H21F2N6O3 [M+H]+ 431. found 431.
