Versuchsvorschrift
To a suspension of 1H-indazole-5-carbonitrile (0.235 g, 1.64 mmol) in THF (6 mL) was added 2 mL of 2 N ammonia in methanol and the flask was charged with 0.05 g Raney® 2800 nickel. A hydrogen balloon was attached to the flask and the system was purged 3 times with hydrogen. After stirring vigorously overnight the reaction mixture was diluted with methanol and filtered through a pad of celite. The solvent was evaporated in vacuo to provide 1-(1H-indazole-5-yl)methanamine.
