Versuchsvorschrift

A solution of 23.4 g (0.12 mole) of 2,6-dimethylaniline and 40.5 g (0.19 mole) of p-toluenesulfonyl chloride in 75 ml of pyridine was heated at reflux for three hours. The mixture was cooled and poured into vigorously stirred 2N hydrochloric acid. The crude product was recrystallized from ethanol to give 45 g of the title compound. Structure assignment was supported by the nmr spectrum and by elemental analysis.
