Reaction Steps

To a mixture of 150 ml of ethylene chloride and 150 ml of water are added 30.3 g of 2-phenylethylamine, 12 g of sodium hydroxide and 0.5 g of tetrabutylammonium bromide. 65.5 g of 4-chlorobenzenesulphonic acid chloride are added to the mixture in batches with stirring. After 30 minutes the organic phase is separated off, evaporated down and the residue is recrystallised from toluene.
