Reaction Steps
Into a 100-mL round-bottom flask, was placed [4-(4-chlorophenyl)-2-(trifluoromethyl)thiophen-3-yl]methyl methanesulfonate (636 mg, 1.72 mmol, 1.00 equiv), ethyl 3-(3,5-difluoro-4-hydroxyphenyl)propanoate (514 mg, 2.23 mmol, 1.30 equiv), potassium carbonate (712 mg, 5.15 mmol, 3.00 equiv), N,N-dimethylformamide (10.0 mL). The resulting solution was stirred overnight at 25° C. The reaction progress was monitored by TLC (ethyl acetate/petroleum ether=1:6). The resulting solution was diluted with 20 mL of H2O. The resulting solution was extracted with 4×20 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 (1:4). This resulted in 0.865 g (100%) of ethyl 3-(4-[[4-(4-chlorophenyl)-2-(trifluoromethyl)thiophen-3-yl]methoxy]-3,5-difluorophenyl)propanoate as colorless oil. Mass spectrum (ESI, m/z): Calcd. for C23H18C1F5O3S, 505.1 (M+H). found 505.1.
