Reaction Conditions

Reaction Steps

5.8 g of sodium phenate were added to a mixture of 50 ml of benzene, 10 ml of dimethylformamide and 8.5 g of 3-chloromethyl-5-chloro-[1,2,4]-thiadiazole and the mixture was stirred at 20° C. for 24 hours. 50 ml of water were added to the mixture and the decanted aqueous phase was extracted with benzene. The combined organic phase was dried and evaporated to dryness. The oil residue was distilled under reduced pressure to obtain 7.2 g of 3-chloromethyl-5-phenoxy-[1,2,4]-thiadiazole boiling at 114°-116° C. at 0.5 mm Hg.
