実験手順

Into a 50-mL round-bottom flask, was placed [3-(4-ethylphenyl)-5-(trifluoromethyl)-1,2-thiazol-4-yl]methanol (50 mg, 0.17 mmol, 1.00 equiv), triethylamine (53 mg, 0.52 mmol, 3.01 equiv), dichloromethane (2.0 mL), MsCl (40 mg, 0.35 mmol, 2.02 equiv). The resulting solution was stirred for 0.5 h at 25° C. The reaction progress was monitored by LCMS. The reaction was then quenched by the addition of 10 mL of water. The resulting solution 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 75 mg of [3-(4-ethylphenyl)-5-(trifluoromethyl)-1,2-thiazol-4-yl]methyl methanesulfonate as a light yellow solid. The crude could be used for the next step directly. Mass spectrum (ESI, m/z): Calcd. for C14H14F3NO3S2, 366.0 (M+H). found 366.0.
