실험 절차

4-(2-Bromo-2-fluoro-acetyl)-benzoic acid methyl ester (1.18 mmol) and 4-methyl-piperazine-1-carbothioic acid amide (1.18 mmol) were dissolved in ethanol (10 mL). The reaction was heated at reflux for 2 h. The reaction was cooled to RT causing the product to precipitate. The product was collected by filtration and washed with cold ethanol. The product was given an aqueous sodium bicarbonate work up to yield the title compound as a colourless oil (74%). MS (ES+) 337 (M+H, 100%).
