Procedure
A stirred solution of (R)-3-quinuclidinol (2.5 g, 19.66 mmol) in acetonitrile (200 mL) was added with trichloromethyl chloroformate (3.06 mL, 25.57 mmol) dropwise at 0° C. and the mixture was allowed to stir at 0° C. for 1 h. The reaction mixture was then stirred at room temperature for 16 h and then the solvent was removed in vacuo to afford the title compound as a white solid (4.39 g, 98%).
