FIELD: biotechnologies.
SUBSTANCE: invention relates to the method of production of 3,7-dithia-1,5-diazabicyclo[3.3.1]nonane of general formula 
. The substance of the method consists in interaction of thiomethylaing mixtute, previously produced by hydrogen sulfide bubbling via 37% water solution of formaldehyde with water solution of ammonia chloride at the molar ratio of NH4Cl: CH2O : H2S = 10 : (25-35): (25-35), at temperature -5÷5°C within 4-8 hrs. A selective (100%) method is developed to produce 3,7-dithia-1,5-diazabicyclo[3,3.1]nonane, which may find application as a fungicide agent in respect to mould fungi.
EFFECT: method improvement.
