✦ Synopsis

Hydrazonoyl halides have been caused

to react with each of methyl 5-ethoxycarbonyl-4-methylthiazole-2-aminothiocarbamate, benzyl 5-ethoxycarbonyl-4-methylthiazole-2-aminothiocarbamate, and 5-ethoxycarbonyl-4-methylthiazol-2-ylphenylthiourea in the presence of triethylamine to give 2-imino-(5-ethoxycarbonyl-4-methyl)thiazolyl-2,3-dihydro-1,3, 4-thiadiazoles in good yields. Structures of the new compounds were elucidated on the basis of elemental analyses, spectral data, and alternative methods of synthesis whenever possible.
