참여 물질

반응 단계

To 10 ml of methylene chloride were added 0.50 g (2.1 mmol) of 4-methyl-N-(4-methylphenyl)-1,2,3-thiadiazole-5-carboxamide and 0.50 g (3.3 mmol) of N-(chlorosulfenyl)morpholine. Then, 0.33 g (3.3 mmol) of triethylamine was slowly added thereto, and the resulting mixture was reacted with stirring for 5 hours. After the reaction was completed, the reaction mixture containing the objective product was poured into water, the objective product was extracted with ethyl acetate, the organic layer was washed with water and dried on anhydrous sodium sulfate, the solvent was distilled off under reduced pressure, and the crude crystal thus obtained was washed with ether. As a result, 0.38 g of the objective compound was obtained (Property: m.p. 60° C. (decomposed); Yield: 52%).
