摘要

TITLE: NEW METHOD FOR THE SYNTHESIS OF5-THIO-1,2,3-THIADIAZOLEABSTRACT OF THE DISCLOSUREThis disclosure describes a novel process for thesynthesis of 5-mercapto-1,2,3-thiadiazoles which are useful asintermediates in the preparation of antibacterial agents. Thisprocess uses as a new intermediate a compound of the formulain which R1 is para toluene sulfonyl, carbamoyl or carboalkoxy,having from 2 to 4 carbon atoms; R2 is hydrogen or methyl andR3 is C1-C3 alkyl.
