Procedure

740 mg of trans-1,4-diaminocyclohexane is taken to approximately 150° C. then 466 mg of the product obtained in Stage 1 above is added, the reaction medium is maintained under agitation at 140° C. for 6 hours then left to return to ambient temperature. Then 15 ml of water is added, followed by extracting with dichloromethane, drying and evaporating the solvent. The residue is chromatographed on silica (eluent: MeOH/NH4OH 98/2), 270 mg of the product obtained is removed and taken up in 10 ml of ethanol, 6 ml of an ethanolic solution of hydrochloric acid is added, followed by separating, washing with ether, drying under reduced pressure at 60° C. and 79 mg of expected product is recovered.
