Versuchsvorschrift

A solution of cyanuryl chloride (18 g) in hot acetone (70 ml) is poured under stirring into water (40 ml). To the so obtained suspension is added, while keeping the temperature to 5° C., 2,3-xylidine (24 ml). Stirring is maintained for 1 hour at 5° C.; then the reaction mixture is filtered, the precipitate is washed with water to neutrality; it is dissolved in ethyl acetate; the solution is dried over Na2SO4. By concentration 16.8 g of the desired compound are obtained. M.p. 186°-188° C. (ethyl acetate/hexane).
