To a 20 mL round-bottomed flask equipped with condenser and N2 inlet were added 121 mg (0.633 mml) 4-hydroxy-N-benzylpiperidine and 5 mL dry dimethylformamide, followed by 32 mg (0.791 mmol) sodium hydride (60% in oil). The reaction was heated to 70° C. to ensure complete formation of the alkoxide, and then 100 mg (0.316 mmol) 2-(2,5-dimethylpyrrolyl)-6-(4-fluoro-naphth-1-yl)pyridine in 2 mL dry dimethylformamide was added, and the reaction was heated at 80° C. for 10 min. The reaction was cooled, poured into water, and extracted into ethyl acetate. After combining with another run on a larger scale, the combined organic layer was washed with brine, dried over sodium sulfate, and evaporated. The residue was chromatographed on silica gel using methanol/methylene chloride as eluant to afford 489 mg (54%) of an oil.
