Reaction Steps

Combine 14.4 gm of diaminooctane, 20.3 ml of benzaldehyde and 0.66 gm of Pt2O in 100 ml of ethanol. Treat the resulting mixture with hydrogen at 45 lbs./sq.in. until no further hydrogen is taken up. Filter, evaporate the solvent (in vacuo), and distill the rendered material to obtain 25.5 gm of the desired product, bp 185°-190° C. at 0.1 mm.
