Versuchsvorschrift

The preparation comprises dissolving cis-8-benzyl-2,8-diazabicyclo[4,3,0]nonane (5.0 g, 23.1 mmol) in dichloromethane (50 mL) and triethylamine (5 mL) under stirring in ice bath, dropwise adding a solution of acetyl chloride (1.8 g, 23.1 mmol) in chloroform (10 mL), continuing with the stirring until the reaction finishes, distilling off the solvent, and chromatographing on silica gel with petroleum ether and ethyl acetate to give cis-8-benzyl-2-acetyl-2,8-diazabicyclo[4,3,0]nonane (5.1 g, 85.5%).
