実験手順

24.4 g of the sodium salt of 2-chloro-5-nitrobenzenesulphinic acid are dissolved in 150 ml of ethanol under reflux conditions, and 35 g of benzyl chloride are gradually added. After 10 to 12 hours under reflux conditions the solution is cooled down to 60° C., and the precipitated salt is separated off by filtration. The solution, on cooling down to 0° C., yields 24.1 g of colourless crystals of benzyl 2-chloro-5-nitrophenyl sulphone.
