Procedure

Using a method similar to Example 1, a mixture of 244 parts of methyl 4-formyl-4-(β-methoxycarbonylethyl)-hexanoate and 2.4 parts of CoCl2.6H2O is reacted with 100 parts of oxygen in the course of 5 hours. The batch is then washed with water, dried with anhydrous magnesium sulfate and subjected to fractional distillation. 113 parts (56% of theory) of γ-ethyl-γ-(β'-methoxycarbonylethyl)-γ-butyrolactone (boiling point 125° C./0.5 mbar) are obtained.
