To a solution of 8.7 mL (74.8 mmol) of trichloromethyl chloroformate in 240 mL of dichloromethane, a solution of 4.75 g (37.4 mmol) of (R)-3-quinuclidol in 240 mL of dichloromethane was added dropwise at 0° C. in inert atmosphere and with continuous stirring. Then, the mixture was stirred at room temperature for 24 h, and the solvent was distilled off under reduced pressure to give 8.46 g (37.4 mmol) of a white solid corresponding to the title compound. IR (KBr, cm−1): 3380, 2650-2500, 1776.
