Reaction Conditions

Temperature27 °C

Reaction Steps

In 52 g of dioxane, 12.5 g of methacrylamide and 1.0 g of sodium ethoxide (NaOEt) were dissolved and the solution was stirred for 20 minutes at the temperature of 27° C. Then, 4.0 g of ethyl chloroformate acid was dissolved in 2 g of dioxane and the solution was added in two portions into the above reaction solution. After leaving it for one day, the solution was neutralized with conc. hydrochloric acid and was extracted with chloroform. The extract was evaporated in vacuo. The crude product was subjected to column chromatography, thereby obtaining 0.44 g of ethyl N-methacryloylcarbamate. Melting point of the compound was 73°-74° C.
