Procedure

A solution of 25.0 g of the product from Example 1 in 340 ml dry acetone and 140 ml dry tetrahydrofuran was treated at 0° C. with 21.5 ml of liquid trimethylamine, added over a period of 10 minutes. The resulting thick white reaction mixture was stirred at room temperature for 3 hours. Filtration under nitrogen and drying in vacuo gave 30.4 g of trimethyl(4,6-dimethoxy-1,3,5-triazin-2-yl)ammonium chloride as a white powder, m.p. 130°-134° C.
