Procedure
Acetyl chloride (5 eq.) was added to an ice-cold solution of 9-((R)-quinuclidin-3-ylcarbamoyl)-3-azaspiro[5.5]undecane-3-carboxylate (0.271 mmol, 1 eq.) in ethanol. The reaction mixture was stirred at room temperature overnight. The solvent was removed in vacuo and the residue dissolved in acetone/ethanol (1:3, 3 ml) and diethyl ether (20 ml) was added. The white solid was filtered out, washed with diethyl ether and dried in vacuo. Yield: 86%
