PROCEDURE

实验过程

(S)-tert-butyl 1-(N-(4-(3-hydroxy-3-methylbut-1-ynyl)thiazol-2-yl)-tert-butoxylcarbonylamino)-3-(4-(trifluoromethyl)phenyl)propan-2-ylcarbamate (0.18 g, 0.31 mmol) was taken up in 5 mL of CCl4 and NBS (0.11 g, 0.62 mmol) was added. After 3 hours, the solvent was removed under reduced pressure, and the residue was purified by flash chromatography on silica gel (5% to 40% EtOAc/hexanes) to afford (S)-tert-butyl 1-(N-(5-bromo-4-(3-hydroxy-3-methylbut-1-ynyl)thiazol-2-yl)-tert-butoxylcarbonylamino)-3-(4-(trifluoromethyl)phenyl)propan-2-ylcarbamate (0.05 g, 24% yield) as a white solid.
