1-Bromo-3-chloropropane → 1-[3-(3-Chloropropoxy)phenyl]ethanone

참여 물질

반응 단계

A mixture of 3′-hydroxyacetophenone (5 g) and 1-bromo-3-chloropropane (5.0 mL) in acetone (40 mL) was treated with potassium carbonate (8.1 g). The mixture was stirred at reflux temperature for 17 hours. The reaction was cooled to ambient temperature and filtered. The filtrate was concentrated in vacuo. The residue was partitioned between dichloromethane (50 mL) and H2O (50 mL). The aqueous phase was washed with two fresh portions of dichloromethane. The combined organic phases were washed with brine, dried over magnesium sulfate, filtered and evaporated to yield the title compound (8.6 g) which was used without further purification.
