To the solution of 4-diethylaminoethoxybenzaldehyde X in 180 ml 10% solution of ammonia in anhydrous ethanol, 4.5 g RaNi was added and the mixture was heated to 80° C. at the pressure 68 atm in the autoclave under hydrogen input to the reaction mixture under stirring for 12 hours. The mixture was cooled, the catalyst was filtered off, washed with ethanol. The solvent was distilled off from the solution and the distillation residue was purified by distillation under the reduced pressure. Afforded 13 g (65%) of 4-diethylaminoethoxybenzylamine XI. Colourless fluid 138-140° C./0.5 torr, n20D=1.520. Lit. [6.7] reports 130° C./0.3 torr, n20D=1.5220.
