1,420 g (8.78 mole) of quinuclidine-3-one-hydrochloride were dissolved in 1800 ml of cold water and at 15° C., 432 g (8.81 mole) of sodium cyanide and 1600 of ml water were added dropwise over one hour followed by stirring for another hour at this temperature. The mixture was filtered, washed with cold water, and dried at 60° C. to obtain 1,290 g (8.48 mole) of 3-cyano-3-hydroxy-quinuclidine (97% yield), in the form of white crystals having a melting point of 157° to 159° C.
