Reaction Steps

A mixture of 190 parts of 3-p-isopropylphenyl-3-methylpropanal, 111 parts of 2-methylmorpholine, 300 parts of methanol and 20 parts of catalyst, comprising 0.5% by weight of Pd, 0.11% by weight of Zn and 0.1% by weight of Cd on Al2O3, is hydrogenated in a stirred autoclave of 1,000 parts by volume capacity, at 120° C. under a hydrogen pressure of 50 bar, until the pressure remains constant. The autoclave is then allowed to cool, the catalyst is filtered off and the filtrate is purified by distillation. 266 parts of N-(3'-(p-isopropylphenyl)-3'-methylpropyl)-2-methylmorpholine, boiling point 122° C./0.05 mm Hg are obtained. The yield is 82% of theory.
