الإجراء التجريبي

—400 ml of acetone cooled to 0° C. are added, under nitrogen stream, with 92.3 g of 2,4,6-trichloro-1,3,5-triazine, then with 38 g of tert-butylamine, always keeping the temperature at about 0° C. After keeping the resulting mixture at this temperature for 30 minutes, 66.7 g of a 30% NaOH aqueous solution, then 400 ml of water are dropped therein, and the resulting mixture is stirred for 1 hour at 0° C. After filtration and washing with water to neutral pH, the resulting precipitate is dried to obtain 108 g of 2-tert-butylamino-4,6-dichloro-1,3,5-triazine. M.p. 129-30° C.
