Acetic Acid → 1,3,5-Triazin-2-amine, 4-methoxy-N,6-dimethyl-

Participants

Reaction Steps

5000 g of a 40% by weight strength methanolic solution of 2,4-dimethoxy-6-methyl-1,3,5-triazine are initially charged and then, at from 5 to 10° C., admixed with a 40% by weight strength aqueous methylamine solution to neutralize the acetic acid, establishing a pH of from 7.2 to 7.5 (glass electrode). At from 13 to 15° C., 1500 g of a 40% by weight strength aqueous methylamine solution are then introduced over a period of 8 hours. After the addition of the methylamine solution has ended, stirring is continued at 14° C. for another 4 hours and then with water-cooling for 12 hours. The reaction product is subsequently filtered off with suction using a nutsch filter and washed with 5×900 ml of a 2% by weight strength methylamine solution and finally with 4×900 ml of water. The yield of 2-methoxy-4-methyl-6-methylamino-1,3,5-triazine, based on the dried product, is 1850 g (yield: about 93%).
