METHOD OF OBTAINING 2,7-DIALKYL-2,3a,5a,7,8a,10a-HEXAAZAPERHYDROPYRENES Russian patent published in 2015 - IPC C07D487/22

Abstract RU 2561506 C1

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining 2,7-dialkyl-2,3a,5a,7,8a,10a-hexaazaperhydropyrenes of general formula (1)

R=n-Pr, i-Pr, n-Bu, t-Bu, cyclo-C₅H₉ characterised by the fact that N,N-bis(methoxymethyl)-N-alkylamines of general formula RN(CH₂OCH₃)₂, where R is given above, are subjected to interaction with 1,4,5,8-tetraazadecalin in methanol-water medium (10:1, volume) in presence of catalyst SmCl₃·6H₂O with molar ratio N,N-bis(methoxymethyl)-N-alkylamine:1,4,5,8-twetraazadecalin:SmCl₃·6H₂O=2:1:(0.03-0.07) at room temperature (~20°C) and atmospheric pressure for 2.5-3.5 h.

EFFECT: obtaining 2,7-dialkyl-2,3a,5a,7,8a,10a-hexaazaperhydropyrenes of general formula (1) with high output.
