Versuchsvorschrift

Cis ethyl 3-bromo-2-oxo-1-azacyclodecane-10-carboxylate (2.96 g, 9.67 mmol) is dissolved in dimethylformamide (30 mL). Silver acetate (6.35 g, 38 mmol) is added, and the reaction is heated to 100° C. for 3 hours. After cooling back to room temperature, the reaction is diluted with ethyl acetate (100 mL), filtered through a pad of silica gel, and the solvent is evaporated to give crude cis ethyl 3-acetoxy-2-oxo-1-azacyclodecane-10-carboxylate.
