FORFARANDE FOR FRAMSTELLNING AV EN ALKALISK LOSNING AV 5-MERKAPTOTETRAZOLYL-1-ETTIKSYRA

摘要

5-Mercaptotetrazolyl-1-acetic acid is prepared by bromination with molecular bromine of tetrazolyl-1-acetic acid to produce 5-bromotetrazolyl-1-acetic acid which is then reacted with thiourea to displace the bromine and, after alkaline hydrolysis, to produce 5-mercaptotetrazolyl-1-acetic acid.
