METHOD FOR PREPARING N-ALKYL-N, N-DI (ALKADIENYL) AMINES Russian patent published in 2017 - IPC C07C211/23 C07C209/68 

FIELD: chemistry.

SUBSTANCE: invention relates to a new method for preparing new N-alkyl-N, N-di (alkadienyl) amines of the formula (1), which can be used as universal precursors for fine organic synthesis and biologically active compounds. The method consists in reacting N, N-bis (ethoxymethyl) -N-alkylamine of the general formula RN (CH₂OEt)₂ (where R = n-Pr, n-Bu, tert-Bu) with α,ω-diacetylene of the general formula HC≡C-CH₂-(CH₂)_n-CH₂-C≡CH (where n=1-4) in the presence of a CuCl catalyst at a molar ratio of N, N-bis (ethoxymethyl) -N-alkylamine: α,ω-diacetylene:CuCl=1:2:(0.03-0.07) in an argon atmosphere at a temperature of 80°C and at the atmospheric pressure in toluene for 5-7 hours.

EFFECT: preparing the desired product with high yield.
