Procedure: To a solution of 0.28 g 1,1-dicyclopropyl-2-dibenzylamino-ethanol (0.00087 mol) in 10 ml methanol was added 0.060 g Pd(OH)2/charcoal (Fluka 7663; 20%) and the mixture was hydrogenated under 8 bar hydrogen pressure at 60° C. for 2 hours. The catalyst was removed by filtration and the mother liquor was concentrated and the residue was purified by chromatography on silicagel with MeCl2/MeOH/NH3 90:10:1 to yield 0.10 g (81% yield) of the title compound as colorless oil. 1H-NMR (CDCl3 300 MHz, δ ppm) 0.28-0.45 (m, 8H); 0.71-0.78 (m, 2H); 2.77 (s, 2H) ppm. The catalyst was removed by filtration the mother liquor was concentrated the residue was purified by chromatography on silicagel with MeCl2/MeOH/NH3 90:10:1
