| Reactant | 3-(Benzothiazol-2-ylthio)-propane-1,2-dicarboxylic acid | HCID 19427537 | — |
| Product | 3-(Benzothiazol-2-ylthio)propane-1,2-dicarboxylic anhydride | HCID 53971181 | — |
Reaction Steps
A suspension of 20 parts 3-(benzothiazol-2-ylthio)-propane-1,2-dicarboxylic acid and 200 parts acetic anhydride is heated at 55° during 1.5 hours. The resulting yellow solution is cooled, poured onto 1000 parts ice-water, stirred until solid to give 3-(benzothiazol-2-ylthio)propane-1,2-dicarboxylic anhydride m.p. 87°-88°.
