実験手順
37.7 g (0.2 mole) of 6-chloro-3-nitro-4-aminophenol are dissolved in 120 ml of dimethoxyethane, 11 g of calcium carbonate are added and 32 g of γ-chloropropyl chloroformate are added dropwise at 70° C. After 1 hour at 90° C., the mixture is filtered hot and the filtrate is stirred into 300 ml of ice-water. The initially oily product crystallises after a short time.
