FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing amide-containing 1,3,5-dithiazinanes of general formula 
, where R=H (Ia), CH3 (Ib). The method is realised by reacting hydrogen sulphide-saturated aldehyde (formal or acetic) with a mixture of isonicotinic acid hydrazide - BuONa (1:3, pH>11.5). The process is carried out at ratio hydrazide: aldehyde: H2S equal to 1:3:2, at temperature 40°C while stirring constantly for 4 hours, followed by neutralisation with a calculated quantity of dilute HCl and purification via column chromatography on SiO2. The substances obtained using the disclosed method can be used as radiation protection, antitumour and diuretic agents, as well as selective sorbents and extractants of noble and precious metals.
EFFECT: obtaining amide-containing 1,3,5-dithiazinanes of general formula (I).
