To a stirred solution of 89.1 g. phosgene in 500 ml. dry ether at -20°C. was added a solution of 30.9 g. N-ethyl-N-2-methoxyethylamine in 50 ml. dry ether, whilst the temperature of the reaction mixture was maintained at -20°C. The stirred mixture was then allowed to warm to room temperature during 1 hour. The reaction mixture was filtered and the filtrate evaporated in vacuo below 25°C. to remove the solvent and give the product, N-(2-methoxyethyl)-N-ethylcarbamoyl chloride as a pale yellow liquid.
