実験手順

To a cold (0° C.) solution of (S)-2-((2-chloro-5-fluoropyrimidin-4-yl)amino)-3,3-dimethylbutan-1-ol, 14a, (1.95 g, 7.87 mmol) and triethylamine (1.37 mL, 9.84 mmol) in dichloromethane (25 mL) was added methanesulfonyl chloride (0.76 mL, 9.84 mmol). The solution was stirred at room temperature for 1 hour. The solvent was removed under reduced pressure and water (100 mL) and EtOAc (50 mL) were added. The organic phase was separated, dried (MgSO4) and concentrated under reduced pressure to afford 2.55 g of the desired product as a pale yellow foamy solid: LC/MS (10-90% ACN/water 5 min with 0.9% FA, C4) m/z 326.99 (M+H) RT=2.96 minutes.
