Procedure
10.0 Parts of 2-amino-6-(4-amino-3-ethylphenyl)-6-methylheptane in 120 parts of 1N aqueous hydrochloric acid were shaken with hydrogen at room temperature and atmospheric pressure with 1.0 parts Nishimura catalyst. After 46% of theory hydrogen had been taken up in 18 hours a further 1.0 parts of catalyst was added and 96% of theory hydrogen uptake was reached in the next 15 hours. The hydrogenation which ceased at 110% theory during the next 24 hours following a final 1.0 part catalyst addition, was worked up according to Example 1, and gave on distillation 8.8 parts of 2-amino-6-(4-amino-3-ethylcyclohexyl)-6-methylheptane b12 176°-80° with the following percentage composition by weight.
