| titleOfInvention | Process for the manufacture of 5-mercapto- 1,2,3-triazoles |
| abstract | ABSTRACT Process for the manufacture of 5-mercapto-1, 2, 3-triazoles 5-Mercapto-1,2,3-triazoles of the formula I (I) (in which R1 represents H or optionally substituted C1-C4-alkyl), suitable as starting materials for the production of antibiotics, preferably cephalosporin derivatives, are prepared by reacting a 1,2,3-thiadiazole-4-R1-5-carboxylic acid azide with an alcohol or phenol to form a (1,2,3-thiadiazol-4-R1-5-yl)-carbamic acid ester, hydrolysing the carbamic acid ester in the presence of an acid or base to form a 5-amino-4-R1-1,2,3-thiadiazole and rearranging the 5-amino-4-R1-1,2,3-thiadiazole in the presence of a base. |
