FIELD: chemistry, pharmacology.
SUBSTANCE: claimed invention relates to method of obtaining N-[1',3',5'- DITHIZIANAN -5'-YL-CARBONYL]-1,3,5-DITHIAZINAN-5-CARBOXAMIDE, which can find application as selective sorbent and extragent of noble and precious metals. Essence of method lies in interaction of saturated with hydrogen sulfate water solution of formaldehyde with water or alcohol solution of carbamyl urea in molar ratio carbamyl urea: formaldehyde: hydrogen sulfate, equal 1:6:4, at temperature 40-80°C and mixing during 6 hours.
EFFECT: obtaining N-[1',3',5'- DITHIAZAN-5'-YL-CARBONYL]-1,3,5-DITHIAZINAN-5-CARBOXAMIDE with output 56-82%.
