Procedure

A mixture of 3-quinuclidinone (20.9 g, 167 mmol), benzaldehyde (17.7 g, 167 mmol), and one pellet of sodium hydroxide in 75 mL of ethanol was refluxed for 1.5 h. After the solution was cooled, the yellow precipitates were collected, washed with ethanol, and dried to give (Z)-2-benzylidenequinuclidin-3-one (32.5 g, yield: 91.2%, mp 130-132° C.).
