Butyllithium (2.5 M, 1.86 ml, 4.64 mmol) was added to a mixture of 2-bromo-6-methoxynaphthalene (1.0 g, 4.22 mmol) and diethyl ether (10 ml) at 20° C. The temperature was kept below 35° C. for 30 min. The mixture was cooled to −70° C. and 3-quinuclidinone (0.53 g, 4.22 mmol) was added at −70° C. The mixture was stirred at −70° C. for 1 h. The mixture was allowed to reach room temperature. Water (1 ml) was added followed by aqueous sodium hydroxide (1 M, 10 ml). The crystalline product was filtered and was washed with cold diethyl ether (2 ml). Yield 0.49 g (41%). Mp >330° C.
