実験手順

1-Chloro-propan-2-one (1.0 g, 11.63 mmol) and potassium carbonate (2.9 g, 21.15 mmol) were added to a solution of 4-bromo-benzenethiol (2.0 g, 10.58 mmol) in DMF (5.0 mL) at 0° C. The resulting mixture was stirred at room temperature overnight. The reaction was monitored by TLC (100% hexane). The reaction mixture quenched with ice and extracted with ethyl acetate. The organic layer was dried over sodium sulfate and concentrated to yield the crude product. Purification by column chromatography on silica gel (2% methanol in chloroform) afforded 2.0 g of the product (80% yield).
