실험 절차

To a solution of 12.9 g (145 mmol) of 2-N,N-dimethylaminoethanol in 100 mL of hexanes, 116 mL (290 mmol) of 2.5 M nBuLi in hexanes was added dropwise with vigorous stirring at −10° C. This mixture was slowly warmed to 0° C., stirred for 30 min, and then 7.54 g (48.6 mmol) of 2-phenylpyridine was added at −10° C. The resulting mixture was stirred for 2 hr at 0° C. and then added dropwise to a solution of 43.2 g (179 mmol) of 16 in 725 mL of THF at −10° C. This mixture was slowly warmed to room temperature, stirred for 12 hr, and then 20 mL of water was added. The organic solvent was evaporated using a rotary evaporator. 17 was isolated from the residue by flash chromatography on silica gel 60 (40-63 um, eluent: from hexanes to hexanes-ethyl acetate=5:1, vol.). The obtained product was additionally washed with 30 mL of diethyl ether and then dried in vacuum. Yield 11.0 g (62%) of white solid.
