Abstract

The invention comprises 4-[2,6,6-trimethyl-4-methoxycyclohexen-yl-1] buten-3-one-2 and a process for preparing it by reacting betaionone with N-bromo succinimide dehydrobrominating and then reacting the trimethylcyclohexadienyl-butenone obtained with methyl sulphate in presence of methanol. Specification 976,833 also is referred to.
