Versuchsvorschrift

3-Nitro-6,7-dihydro-5H-cyclopenta[b]pyridine (C) (340 mg, 2.07 mmol) was dissolved in methanol. Pd/C (40 mg) was added to it. The resulting mixture was stirred at room temperature for 2 h under H2. TLC showed complete consumption of starting material. The mixture was filtered through celite bed and the filtrate was concentrated under reduced pressure to afford desired 6,7-dihydro-5H-cyclopenta[b]pyridin-3-amine (D). (250 mg, 90%)
