A mixture of 500 mg of 5,6-epoxy-4,4-dimethyl-tetrahydro-pyr-2-one, 5 ml of 1,1-dimethyl ethanol and 2.5 mg of p-toluene sulfonic acid was stirred for 41 hours at room temperature and 1 ml of pyridine was then added. The mixture was evaporated to dryness under reduced pressure to obtain 6-(1,1-dimethylethoxy)-5-hydroxy-4,4-dimethyl-tetrahydro-pyr-2-one which was used as is for the next step.
