実験手順

100 g of N-hydroxyurethane and 80.3 g of allyl chloride were added, at 20° C., to a solution of 53.8 g of potassium hydroxide in 750 ml of ethanol. The mixture was stirred and refluxed (80° C.) for 4 hours, then was cooled to 25° C. and filtered. The solvent was evaporated from the filtrate and the residue, an oil, was distilled, 51°-55° C., 0.2 Torr., to give ethyl (2-propenyloxy)carbamate, 3A, as a colorless oil.
