실험 절차

A mixture of 42.2 g of 5A and 50 g of concentrated sulfuric acid in 600 ml of water was refluxed for 7 hours. The resulting mixture was charcoaled, filtered, cooled to 10° C. and made alkaline with sodium hydroxide. The resulting mixture was extracted with ether. The extract was dried and the ether evaporated to give 3-chloro-4-fluoro-N-methyl-aniline, (5B), as a yellow oil.
