実験手順

To a solution of ethyl 1-(4-fluorophenyl)-2-(hydroxymethyl)-1H-imidazole-5-carboxylate (15) (1.25 g, 4.7 mmol) and triethylamine (0.95 g, 9.4 mmol) in CH2Cl2 (30 mL) was added methanesulfonyl chloride (0.65 g, 5.64 mmol) at 0° C. and the reaction was stirred at 0° C. After 3 hours, 2,6-dichlorobenzenethiol (0.84 g mg, 4.7 mmol) and cesium carbonate (2.28 g, 7 mmol) were added and the reaction was stirred at room temperature for 1 hour. The mixture was filtered by vacuum filtration, and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel to afford ethyl 2-(((2,6-dichlorophenyl)thio)methyl)-1-(4-fluorophenyl)-1H-imidazole-5-carboxylate (72).
