METHOD OF OBTAINING 3-PYRIDINYL-1,5,3-DITHIAZOCINANES Russian patent published in 2014 - IPC C07D417/04

Abstract RU 2536231 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of obtaining 3-pyridinyl-1,5,3-dithiazocinanes of formula I . The essence of the method consists in the interaction of N,N-bis(methoxymethyl)-N-pyridineamine with 1,3-propanedithiol in the presence of a catalyst CuCl₂ in a molar ratio N,N-bis(methoxymethyl)-N-pyridineamine: 1,3-propanedithiol: CuCl₂=10:10:(0.3-0.7) at room temperature and atmospheric pressure in chloroform for 120-150 minutes. The output of respective 3-pyridinyl-1,5,3-dithiazocinanes constitutes 54-77%.

EFFECT: method improvement.
