Reaction Steps

A solution of 3-benzylthio-1-(4,6-dimethoxy-1,3,5-triazin-2-yl)-5-methyl-1,2,4-triazole (6 g) in dichloromethane (60 ml) was treated with silica gel (14 g) 60-120 mesh and water (2.8 g). Sulphuryl chloride (10.6 ml) in dichloromethane (12 ml) was added dropwise with stirring whilst maintaining a temperature of 5° C. for 2 hours. The silica gel was filtered off, washed with dichloromethane (150 ml) and ethyl acetate (100 ml), and the combined washings were extracted with water and aqueous sodium bicarbonate. The organic layer was dried and evaporated at 40° C. in vacuo. The residue was triturated with ether and filtered to give 3 g of the desired product.
