N-Methoxychloroacetamide (12.3 grams; 0.1 mole), benzene (80 ml) and dibutyltin dilaurate (1 drop) are charged into a glass reaction flask equipped with a mechanical stirrer, thermometer and reflux condenser. 4-Nitrophenylisocyanate (16.4 grams; 0.1 mole) dissolved in benzene (30 ml) is incrementally added to the reaction mixture, with stirring, at room temperature. After the addition is completed the reaction mixture is heated at reflux for a period of about 4 hours. After this time the reaction mixture is distilled to remove benzene and unreacted starting material thereby yielding the desired product 1-chloro-2-(N-4-nitrophenylcarbamoyloxy)-2-methoxyiminoethane.
