실험 절차

To a stirring suspension of (S)-2-((2-chloro-5-fluoropyrimidin-4-yl)amino)-3,3-dimethylbutane-1-thiol, 77a, (1.50 g, 5.69 mmol) and K2CO3 (2.36 g, 17.06 mmol) in acetone (15 mL) was added tert-butyl bromoacetate (1.26 mL, 8.53 mmol). The suspension was stirred at room temperature for 18 hours. The resulting solid was filtered, washed with acetone and the filtrate was concentrated under reduced pressure. The crude residue was purified by silica gel chromatography (0-30% EtOAc/Hexanes gradient) to afford 1.6 g of the desired product as an off-white solid: LCMS Gradient 10-90%, 0.1% formic acid, 5 minutes, C18/ACN, Retention Time=3.81 minutes (M+H) 378.06.
