실험 절차

A mixture containing 35 g of 4-fluorobenzoyl chloride in 50 ml of 100% ethanol is refluxed for 15 minutes. 35 g of the ethyl 4-fluorobenzoate obtained are mixed with 22 g of imidazole and 61 g of potassium carbonate in 35 ml of DMSO. The mixture is heated for 18 hours at 120°-130° C. and 500 ml of iced water are then added. A precipitate forms and the expected product crystallizes from iso ether.
