실험 절차

A mixture of 28 parts of 4-fluoro-N-(2-hydroxyethyl)-2-nitrobenzamide, 40 parts of thionyl chloride and 150 parts of trichloromethane is stirred and refluxed for 2 hours. After cooling, the precipitated product is filtered off and dried, yielding 24.5 parts (83%) of N-(2-chloroethyl)-4-fluoro-2-nitrobenzamide.
