The operation is carried out as in Stage 3 of Example 5 starting from 536 mg of trans-1,4-diaminocyclohexane and 156 mg of the product obtained in Stage 1 above, the reaction medium is taken to a temperature of approximately 140 to 145° C. for approximately 4 hours 30 minutes then left to return to ambient temperature. After purification on silica eluting with methanol/ammonium hydroxide (NH4OH) in a proportion of 98/2 salification is carried out with 1.4 N hydrochloric acid in ethanol, followed by separating, washing and drying at a temperature of approximately 50° C. In this way 145 mg of expected product is obtained in the form of pink beige crystals.
