Reaktionsschritte

5-Hydroxy-adamantan-2-one (15 g, 90.24 mmol, International Specialty) and Pd/C (1.498 g, Degussa 19985880, 5%, 50% water) were added to a Parr reactor, followed by ammonia in methanol solution (7N, 300.4 ml, 2.1 mol). The reactor was pressurized with hydrogen at 200-250 psi for 18 h. The mixture was then filtered over a pad of celite and concentrated in vacuo to give 4-amino-adamantan-1-ol (15.15 g, 4/1=trans/cis by NMR-D2O) as a white solid. This material is used directly without further purification.
