実験手順
To a cold (0° C.) solution of (S)-2-chloro-N-(3,3-dimethyl-1-(methylthio)butan-2-yl)-5-fluoropyrimidin-4-amine, 78a, (0.15 g, 0.54 mmol) in methanol (10 mL) was added Oxone (0.50 g, 0.81 mmol). The solution was stirred at room temperature for 3 hours. The solution was concentrated in vacuo to give a white residue which was dissolved in water (10 mL). The aqueous layer was extracted with EtOAc (3×10 mL). The combined organic phases were dried (MgSO4), filtered and concentrated in vacuo to afford 150 mg of the desired product as a white solid: LC/MS (60-90% ACN/water 5 min with 0.9% FA) m/z 310.31 (M+H) RT=2.60 minutes.
