Reaction Conditions

Reaction Steps

10 g of 1-{Benzyl-[2-(2-methoxy-phenoxy)-ethyl]-amino}-3-(9H-carbazol-4-yloxy)-propan-2-ol (20 mmol) were dissolved in 80 ml methanol. 1 g of Pd—C (10%) were added and the suspension was warmed to 50° C. The mixture was hydrogenated at normal pressure for about 7 hours. The Pd-catalyst was filtered under suction and washed with 25 ml of hot methanol. 80 ml of methanol were distilled off and the residue was cooled to 0° C. and hold at this temperature for 6 h. The product was filtered and washed twice with 3 ml cold methanol. The substance was dried at 60° C. for 12 h.
