564 parts of 1,1-dimethoxy-2-methyl-2-acetoxy-but-3-ene and 0.3 part of copper (I) chloride were heated, with stirring, at 160° C. in a reaction vessel equipped with a stirrer, an internal thermometer and a reflux condenser. During the reaction time of 4 hours, the reaction temperature gradually fell to 146° C. as a result of the low-boiling products formed beginning to reflux. Subsequent working up of the reaction mixture by distillation gave 422 parts of 4,4-dimethoxy-3-methyl-crotyl acetate, corresponding to a yield of 74.8% of theory.
