실험 절차

To a solution of 655 mg (4.8 mmol) of 2-chlorophenylacetylene in 10 mL of tetrahydrofuran (THF) cooled to −78° C. under a nitrogen atmosphere was added 3.0 mL (4.8 mmol) of 1.6M n-butyllithium in hexane. The solution was stirred at −78° C. for 2 hrs, and then a solution of 514 mg (4.8 mmol) of 3-pyridinecarboxaldehyde in 2.5 mL of tetrahydrofuran (THF) was added. After 3.5 hrs, the reaction mixture was poured into water. The organic product was extracted with ether several times. Combined ether extracts were washed with saturated sodium bicarbonate and dried over magnesium sulfate. The drying agent was filtered off, and the ether was removed by rotoevaporation to give the oily 3-(2-chlorophenyl)-1-(3-pyridyl)-2-propyn-1-ol.
