실험 절차

Into a 100-mL round-bottom flask, was placed [3-(4-ethylphenyl)-5-(pentafluoroethyl)-1,2-thiazol-4-yl]methanol (108 mg, 0.32 mmol, 1.00 equiv), dichloromethane (10 mL). The solution was cooled to 0 degree C. MsCl (73 mg, 0.64 mmol, 2.00 equiv) and triethylamine (0.097 g, 0.96 mmol, 3.00 equiv) were added dropwise. The resulting solution was stirred for 2 h at 25° C. The reaction progress was monitored by LCMS. The reaction was then quenched by the addition of 5 mL of water. Organic phase was separated and the aqueous phase was extracted with 3×10 mL of dichloromethane and the organic layers combined. The resulting mixture was washed with 2×20 mL of sodium chloride. The mixture was dried over anhydrous sodium sulfate and concentrated under vacuum. This resulted in 0.150 g (crude) of [3-(4-ethylphenyl)-5-(pentafluoroethyl)-1,2-thiazol-4-yl]methyl methanesulfonate as a white solid. And it could been used for the next step directly. Mass spectrum (ESI, m/z): Calcd. for C15H14F5NO3S2, 416.4 (M+H). found 416.4.
