A mixture of 3-methyl-2-cyclopentenone 24.5 g (0.25 mole) and prenyl chloride 54 g (0.51 mole) was fed into a reaction flask containing 30 ml of toluene, sodium hydroxide 21.3 g, water 21.3 g and Aliquat 336 lg maintaining 100° C. The reaction mass was aged for 4 hours, cooled to 25° C. and neutralized with acetic acid. The organic layer was removed and distilled to give 20.5 g of 3-methyl-2-(3-methyl-2-butenyl)-2-cyclopenten-1-one.
