Reaction Steps

A solution of N,N-dimethyl-N'-isobutylidene-1,3-diaminopropane in benzene is prepared by reacting 92 g of 3-dimethylamino-1-propylamine with 65 g of isobutyraldehyde in 200 ml of benzene by separating off the water of reaction azeotropically. This solution is hydrogenated in an autoclave at 90° C. and 125 atmospheres in the presence of 14 g of Raney nickel. Working up by distillation yields 95.6 g of pure product with a boiling point of 75° C./14 mm Hg.
