Versuchsvorschrift

A solution of 5-nitro-2-(2,2,3,3-tetrafluoro-propoxy)pyridine (1.5 g, 0.6 mmol) in methanol (30 ml) was hydrogenated over 10% Pd—C (150 mg) at atmospheric pressure until no further gas was absorbed. The reaction mixture was filtered over celite and the filtrate concentrated to dryness to yield 6-(2,2,3,3-tetrafluoro propoxy)-pyridin-3-ylamine (600 mg, 50%) as solid.
