Participants

Reaction Conditions

Reaction Steps

20 g of sodium hydride (80% strength in paraffin oil) are initially introduced into 500 ml of toluene and 89 g (0.5 mol) of ethyl N-(2,2-dimethoxyethyl)-carbamate are added dropwise at 80° C. The mixture is stirred at 80° C. for one hour and 73 g (0.6 mol) of allyl bromide are then added dropwise in the course of three hours. The mixture is stirred at 80° C. overnight, the salts are dissolved with water and the organic phase is separated off. The aqueous phase is extracted with toluene, the organic phases are dried over potassium carbonate and concentrated and the residue is distilled.
