FIELD: chemistry.
SUBSTANCE: N,S-containing heterocycle obtained using the disclosed method can be used as a selective sorbent and extraction agent for precious metals, and as a special reagent for inhibiting bacterial action in different media. The method involves reaction of hydrogen sulphide-saturated aqueous formaldehyde solution with o-aminothiophenol in the presence of EtOH at 20-80°C and stirring for 3 hours. Output of the desired product is equal to 79% at 20°C and 83% at 80°C.
EFFECT: high output.
