1-Bromo-3-chloropropane → 3-(p-Acetyl-m-methoxyphenoxy)propyl chloride

Participants

Reaction Steps

A mixture of 10.6 g (0.637 mole) of 1-(4-hydroxy-2-methoxyphenyl)ethanone, 20 g (0.127 mole) of 1-bromo-3-chloropropane and 26.4 g (0.19 mole) of anhydrous potassium carbonate in 250 ml of acetone was heated at reflux for 20 hr. The mixture was cooled, filtered and the filtrate concentrated under vacuum pump pressure at 90° C. to give an oil which gradually crystallized. The solid was triturated with petroleum ether (30°-60° C.), collected by filtration and dried to yield 14.6 g (94%) of white solid, m.p. 47°-49° C. on recrystallizing from isopropyl ether.
