Participants

Reaction Steps

To 50 ml of acetonitrile were added 7.0 g (47 mmol) of 5-chloromethyl-4-methyl-1,2,3-thiadiazole and 9.0 g (94 mmol) of sodium formimide. After stirring the resulting mixture for 16 hours with heating under reflux, the reaction mixture was cooled to the room temperature, a saturated aqueous solution of sodium chloride was added, the objective product was extracted with ethyl acetate, the organic layer was washed with water and dried, and the solvent was distilled off under reduced pressure. Then, while stirring the resulting crystalline product together with 40 ml of water, 30 ml of concentrated hydrochloric acid was added. After ten minutes, water and hydrochloric acid were distilled off, and the residue was washed with ethyl acetate. Thus, 6.6 g of the objective compound was obtained.
