Sulfuryl chloride → HCID 21266811, compound

Participants

Reaction Steps

26.7 g (0.19 mol) of sulfuryl chloride were added dropwise with ice-cooling to a suspension of 24 g (98 mmol) of 4-(4-chlorophenyl)-1-difluoromethyl-2-methyl-1H-imidazole in 200 ml of tetrachloromethane. After the reaction mixture had been stirred for 2 hours, an excess of saturated aqueous sodium hydrogen carbonate solution was added dropwise (still with ice-cooling). The solids were subsequently filtered off. The organic phase was washed with water until neutral, dried over magnesium sulfate and concentrated. The crude product was purified by means of silica gel column chromatography (eluent: hexane/ethyl acetate=8:1). Yield: 7.4 g.
