Process for the preparation of the sulfate salt of 2-amino-5-alkylthio-1,3,4-thiadiazoles

摘要

Disclosed is a novel process for the preparation of the sulfate salt of 2-amino-5-alkylthio-1,3,4-thiadiazoles, which comprises reacting 2,5-dithiobiurea with a dialkylsulfate. Derivatives of compounds produced by this novel process are useful as chemical synthetic intermediates in the preparation of organic dyes and pharmaceuticals.
