실험 절차

(S)-tert-butyl 1-(N-(4-bromothiazol-2-yl)-tert-butoxylcarbonylamino)-3-(4-(trifluoromethyl)phenyl)propan-2-ylcarbamate (0.25 g, 0.43 mmol) was taken up in 4 mL of Et3N. 2-Methylbut-3-yn-2-ol (0.21 mL, 2.2 mmol), dichlorobis(triphenylphosphino)-palladium(II) (0.030 g, 0.043 mmol), and copper(I) iodide (0.025 g, 0.13 mmol) were added. The mixture was stirred for 20 minutes. No reaction was observed, and the mixture was heated to 60° C. for 1 hour. The reaction was judged to be complete by LC/MS, the solvent was removed under reduced pressure, and the residue was purified by flash chromatography on silica gel (5% to 30% EtOAc/hexanes), to provide (S)-tert-butyl 1-(N-(4-(3-hydroxy-3-methylbut-1-ynyl)thiazol-2-yl)-tert-butoxylcarbonylamino)-3-(4-(trifluoromethyl)phenyl)propan-2-ylcarbamate (0.23 g, 91% yield): LCMS (M+H) 584 calc. for C28H37F3N3O5S 583.6.
