Reaction Steps

Into a 50-mL round-bottom flask, was placed [3-chloro-5-(4-chlorophenyl)-1,2-thiazol-4-yl]methyl methanesulfonate (320 mg, 0.95 mmol, 1.00 equiv), ethyl 3-(3,5-difluoro-4-hydroxyphenyl)propanoate (230 mg, 1.00 mmol, 1.06 equiv), potassium carbonate (420 mg, 3.04 mmol, 3.21 equiv), N,N-dimethylformamide (10 mL). The resulting solution was stirred overnight at 30° C. The resulting solution was diluted with of H2O. The resulting solution was extracted with 3×10 mL of ethyl acetate and the organic layers combined and dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (17/83). The collected fractions were combined and concentrated under vacuum. This resulted in 340 mg (68%) of ethyl 3-(4-[[3-chloro-5-(4-chlorophenyl)-1,2-thiazol-4-yl]methoxy]-3,5-difluorophenyl)propanoate as colorless oil. Mass spectrum (ESI, m/z): Calcd. for C21H17C12F2NO3S, 472.0 (M+H). found 472.0.
