Procedure

22 g (0.24 mol) of 3-chloro-1-butene are added to 35.5 g (0.2 mol) of ethyl N-(2,2-dimethoxyethyl)-carbamate and 26 g of powdered potassium hydroxide in 400 ml of dimethylformamide and the mixture is warmed overnight to 40° C. The salts are dissolved with water and the mixture is extracted several times with methylene chloride. The organic extracts are dried over potassium carbonate and concentrated, and the residue is distilled.
