A mixture of 100 mmole of the above-prepared 2-hydroxy4,4-dimethyl-γ-butyrolactone, 150 mmole of methacrylic chloride, 150 mmole of triethylamine, and 300 ml of toluene was stirred at 25° C. for 4 hours. Water was added to the reaction mixture, the organic layer was then concentrated, and the concentrate was subjected to column chromatography on a silica gel to yield 2-methacryloyloxy-4,4-dimethyl-γ-butyrolactone in a yield of 85%.
