Versuchsvorschrift

3-[4-(2-Benzyloxy-4-ethyl-phenoxy)-3-fluoro-phenylamino]-propan-1-ol (400 mg, 1.01 mmol) was taken in 15 ml of absolute ethanol, under nitrogen. To this was added Pd(OH)2, (20%, 50 mg) followed by ammonium formate (200 mg, 3.1 mmol). The reaction mixture was heated at 65° C. and monitored by TLC. After complete consumption of starting material (20 minutes), the heating was stopped and mixture cooled to rt. The reaction mixture was filtered through celite and the residue was washed with methanol. The combined filtrate was concentrated to obtain 300 mg of crude compound showing 70% by HPLC. The crude was purified by preparative HPLC (Column: C18 Symmetry (300×19 mm), 7μ, Mobile phase A: 20 mM ammonium acetate, Mobile phase B: Acetonitrile) to get 140 mg (45.3%) of title compound.
