METHOD OF PRODUCING 2,7-DICYCLOALKYL-4,9-DIMETHYL-2,3A,5A,7,8A,10A-HEXAAZAPERHYDROPYRENES Russian patent published in 2019 - IPC C07D487/22 

Abstract RU 2688221 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing 2,7-dicycloalkyl-4,9-dimethyl-2,3a,5a,7,8a,10a-hexaazaperhydropyrenes of general formula (1), in which R is cyclo-C3H5, cyclo-C5H9, cyclo-C6H11, cyclo-C7H13, cyclo-C8H15, norbornyl-, consisting in reaction of 1,3,5-tricycloalkyl-1,3,5-triazine with 2,6-dimethyl-1,4,5,8-tetraazadecalin in medium of CH3OH-H2O in presence of NiCl2⋅6H2O catalyst in molar ratio of 1,3,5-tricycloalkyl-1,3,5-triazine : 2,6-dimethyl-1,4,5,8-tetraazadecalin : NiCl2⋅6H2O = 2:1:(0.03–0.07) at room temperature (~20 °C) temperature and atmospheric pressure for 2.5–3.5 hours 1.

EFFECT: technical result: obtaining novel 2,7-dicycloalkyl-4,9-dimethyl-2,3a,5a,7,8a,10a-hexaazaperhydropyren of general formula (1) with high output.
