Procedure

A solution of 7 g of 4-butyl-4-hydroxy-3,5,5-trimethyl-2-cyclohexen-1-one (prepared by the procedure of Example IV) in hexane is stirred overnight with 10 ml of a 5% solution of HCl. The hexane is separated and evaporated, and the residue is distilled through a micro column using triethanolamine as a still base. The product obtained is 4-butyl-3,4,5-trimethyl-(2,5-cyclohexadien-1-one, boiling point 112°-119° C. at 0.1 mm Hg. The compound exhibits the following spectral characteristics:
