Versuchsvorschrift

A solution obtained by dissolving 0.50 g of 10-benzyl-3,10-diazabicyclo[4.3.1]decan-4-one (1py1) in THF (4 ml) is dripped in a suspension of LiAlH4 (0.19 g) in anhydrous THF (9 ml), cooled at 0° C., kept under an argon inert atmosphere. The mixture is kept under stirring at room temperature for 14 hours. At the end the mixture is cooled to 0° C. About 0.9 ml of H2O are cautiously added while stirring for 10 min. A precipitate is obtained which is filtered under vacuum and washed with dichloromethane. The recovered filtrate is evaporated, obtaining an oil which is dissolved in dichloromethane. The organic solution is dehydrated with sodium sulphate and the solvent then evaporated. 0.47 g of the compound 10-benzyl-3,10-diazabicyclo[4.3.1]decane are recovered. Yield: quantitative; Rf: 0.62 (CH2Cl2-MeOH 8:2); 1H-NMR (CDCl3): δ (ppm) 1.17-2.18 (m, 8H), 2.62 (bs, 1H), 2.76-2.92 (m, 2H), 2.99-3.18 (m, 4H), 3.97 (s, 2H), 7.20-7.42 (m, 5H).
