実験手順

Within a period of half an hour, 10 g (0.1 mol) of triethylamine was added dropwise to a suspension of 35 g (0.1 mol) of 3-ethyl-2-methyl-benzothiazolium-p-toluene-sulfonate and 43 g (0.1 mol) of tris-trichloromethyl-s-triazine in 300 ml of toluene. After completion of the addition the reaction mixture was stirred for half an hour, until the exothermic reaction ceased; the product which had precipitated was filtered off and dried. Compound 2 was obtained in nearly pure form in a quantity of 40 g. By evaporating the toluene in vacuo and treating the solid residue with ethanol, another 9 g of the product resulted. After recrystallization from 2-methoxy-ethanol 40 g (82%) of yellow needles of melting point 238° to 241° C. were obtained.
