Methanethiol is passed into a solution of 18.5 g of cyanuric chloride in 200 ml of acetone at a temperature of -25° to -30° C. 13.5 ml of collidine are then added slowly at the same temperature, whereupon collidine hydrochloride precipitates. The mixture is left to stand for 1 hour at 0° C. and is then poured onto ice, whereupon a white crystalline substance precipitates. After filtering the mixture, washing the product with water and drying it in a desiccator, 17.5 g of 2-methylthio-4,6-dichloro-1,3,5-triazine with a melting point of 57° to 59° C. are obtained.
