Potassium Iodide → HCID 54082516, compound

Participants

Reaction Steps

2.35 g (0.017 mol) of potassium carbonate and 50 mg of potassium iodide are added to a solution of 4.0 g (0.017 mol) of 1-bromo-6-isopropoxy-4-methyl-3-hexene and 2.35 g (0.017 mol) of 3,4-methylendioxy-phenol in 120 cc of acetone. The suspension is boiled under reflux during the course of 20 hours, is then filtered and liberated from acetone in a vacuum. The residue is taken up in ether, washed with water and saturated salt solution, dried over sodium sulphate and evaporated. The residue is chromatographed on silica gel with hexane/ethyl acetate 9 : 1. Thus the cis/trans isomeric mixture of the 5-(6-isopropoxy-4-methyl methyl-3-hexenyloxy)-1,3-benzodioxol is obtained as colourless oil. nD20 = 1.5111.
