Trimethylamine → 2-Propargyloxycarbonyloxyethyl Methacrylate

Participants

Reaction Steps

A flask use in Example 1 was charged with 19.3 g of 2-methacryloyloxyethyl chloroformate and 11.5 g of trimethylamine in 50.0 g of methylene chloride. To the flask was added 7.0 g of propargyl alcohol dropwise over one hour. The mixture was allowed to react for 6 hours at 30° C. After the reaction, the mixture was processed as in Example 1 to give 2-propargyloxycarbonyloxyethyl methacrylate as colorless liquid. Yield, 53.6% of theory. The product was identified to be the same as the product of Example 1 by the IR spectrum and 1H--NMR.
