Reaction Conditions

Reaction Steps

36.8 g (0.2 mol) of cyanuric chloride are added in the course of 2 hours, at 0°-5° C., to a mixture of 200 ml of methanol, 25 ml of water and 33.6 g (0.4 mol) of sodium bicarbonate. The reaction mixture is stirred, first for one hour at about 3° C. and then for about 30 minutes at 30° C., until the evolution of CO2 has ceased. The white suspension is washed with 100 ml of water and the product is filtered off and dried at 60° C. in a drying cabinet. Recrystallisation from hexane yields 19.6 g of 2-methoxy-4,6-dichloro-1,3,5-triazine with a melting point at about 90° C.
