. The method is realised by reacting a cyclic ketone with an amine derivative and formic acid in the presence of a catalyst. The cyclic ketones used include cyclopentanone, cyclohexanone and 2-adamantanone, and the amine derivative used is formamide, cyclohexylamine, piperidine, morpholine, piperazine, 2-aminoethanol, 1,2-ethylenediamine, and the catalyst used is copper nanoparticles. The process is carried out in molar ratio ketone: amine derivative: HCOOH equal to 1:3-4:5-10, at temperature 100°C for 3-9 hours. The copper nanoparticles can be obtained in situ, as well as beforehand.
EFFECT: high output of cycloalkylamines under milder conditions for carrying out the process.
