Conditions

Temperature
140 °C

Procedure

2 g of trans-1,4-diaminocyclohexane is taken to approximately 150° C. then 1.18 g of the product obtained in Stage 1 above is added, the reaction medium is maintained under agitation to 140° C. for 6 hours then left to return to ambient temperature. Then 30 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), 130 mg of the product obtained is removed and taken up in 10 ml of ethanol, 4 ml of an ethanolic solution of hydrochloric acid is added, followed by separating, washing with ether, drying under reduced pressure at 50° C. and 144 mg of expected product is recovered.
