2-Aroyl-5-aroylamino-1,2,4-thiadiazolin-3-ones (2) have been synthesized through aroylation of 5-arruno-2H-1,2,4-thiadiazolin-3-one (1) as an analog of cytosine. The aroylation was carried out with a substituted aroyl chloride in pyridine at 56∼58°C. It has been established that the intermediates of the reactions are 2-aroyl-5-amino-1,2,4-thiadiazolin-3-ones (3) on the basis of the spectral data, additional
