Procedure

To a solution of sodium tetraphenylborate (1.90 g) in acetone (8 ml) at 20° C. was added aqueous 4-azoniaspiro[3,4]octane chloride (1.64 ml, prepared as above). The resulting solid was filtered, washed with water (3×10 ml) and dried in a vacuum oven to give 4-azoniaspiro[3,4]octane tetraphenylborate (2.17 g, 90% of theory).
