NOVEL 4-(AZACYCLOALKYL)PHTHALONITRILES AND SYNTHESIS METHOD THEREOF Russian patent published in 2012 - IPC C07C255/51 C07D207/09 C07D211/26 C07D241/04

Abstract RU 2447061 C1

FIELD: chemistry.

SUBSTANCE: invention relates to synthesis of novel 4-(azacycloalkyl)phthalonitriles. Novel 4-(azacycloalkyl)phthalonitriles of general formula

are obtained. The method of obtaining said compounds involves nucleophilic substitution of the bromine atom in 4-bromophthalonitrile (BPN) with N,N-cycloalkyleneamines.

The reaction takes place in the presence of a deprotonation agent K₂CO₃ and a catalytic complex Cul/dipyridyl formed in situ at temperature 90-95°C for 12 hours. Molar ratio of reactants BPN: amine: Cul: dipyridyl: K₂CO₃=1:1.2:0.1:0.1:1.5. After the reaction, the mixture is cooled and filtered. The filtered residue is washed with water and recrystallised.

EFFECT: obtaining novel 4-(azacycloalkyl)phthalonitriles using a method which is safe for this class of compounds.
