1,800 parts of 1,1-dimethoxy-2-methyl-2-acetoxy-but-3-ene together with 3.6 parts of copper (II) acetate were heated, with stirring, for 12 hours at 152° C. in the reaction vessel described under (A). The low-boiling products formed distilled off continuously over the entire reaction period. Subsequent working up of the reaction mixture by distillation gave 1,278 parts of 4,4-dimethoxy-3-methyl-crotyl acetate, corresponding to a yield of 71% of theory.
