Abstract
FIELD: sulfur-containing guanidines. SUBSTANCE: method involves the use of 2-amino-2-thazoline or 5,6-dihydrothazine hydrobromides which were treated with 5-7% aqueous ammonia at the mole ratio 1:2-2.5 and at 50-100 C in inert gas atmosphere. Then CSis added to the reaction mass at 0 C (12 h). The end product is isolated in the form of salt by treatment with required acid. The yield of the end product is increased by 30-60%. EFFECT: increased yield of the end product, simplified process.
