Allyl Alcohol → N-[3-(3-Oxo-propyl)-phenyl]-methanesulfonamide

참여 물질

반응 단계

A mixture of N-(3-iodo-phenyl)-methanesulfonamide (2.4 g, 8 mmol), tetra-n-butyl-ammonium chloride (2.22 g, 8 mmol), allyl alcohol (0.7 g, 12 mmol), sodium hydrogencarbonate (1.6 g, 19 mmol) and palladium(II) chloride (0.36 g, 1.8 mmol) in anhydrous dimethylformamide (30 mL) was stirred at room temperature for 48 h under argon. The mixture was then diluted with 5% aqueous hydrochloric acid (100 mL) and extracted with ethyl acetate (2×100 mL). The combined organic layers were dried (sodium sulfate) and evaporated in vacuo. The crude product was purified by silica gel chromatography (ethyl acetate in hexane, 30% to 50%) to give the title compound as an amber oil (1.1 g, 60%).
