実験手順

Oxone (1.04 g, 1.69 mmol) was added to a stirring solution of (S)-tert-Butyl 2-(2-(2-chloro-5-fluoropyrimidin-4-ylamino)-3,3-dimethyl-butylthio)ethanoate, 168a, (0.53 g, 1.41 mmol) in methanol (20 mL). The solution was stirred for 15 minutes at room temperature. The solution was concentrated to give white residue which was dissolved in water (50 mL). The aqueous layer was extracted with EtOAc (3×25 mL) and the organic layer was dried (MgSO4), filtered and concentrated in vacuo to give 540 mg of the desired product as a white solid: LCMS Gradient 10-90%, 0.1% formic acid, 5 minutes, C18/ACN, Retention Time=3.05 minutes (M+H) 394.28.
