実験手順: 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. After 3.5 hrs The organic product was extracted with ether several times Combined ether extracts were washed with saturated sodium bicarbonate dried over magnesium sulfate The drying agent was filtered off the ether was removed by rotoevaporation

実験手順: A mixture of 2-bromo-4,5-dihydropyrido[4,3-b]thieno[2,3-d]oxepine (140 mg, 0.5 mmol) from Example 72, 1-chloro-2-ethynylbenzene, 18 mg (0.025 mmol) of bistriphenylphosphinepalladium(II) chloride and 1 ml (7.17 mmol) of triethylamine in 4 ml of acetonitrile was degassed. Copper (I) iodide (2.4 mg, 0.012 mmol) was then added and the mixture was heated at 85° C. for 3 hours. The mixture was mixed with 20 ml of water and extracted with 10 ml of ethyl acetate twice. The combined extracts were washed with 1% aqueous ammonia, water, brine and dried over sodium sulfate. The solution was concentrated in vacuum, the residue purified by flash chromatography eluting with 30% ethyl acetate in hexane to give 2-((2-chlorophenyl)ethynyl)-4,5-dihydropyrido[4,3-b]thieno[2,3-d]oxepine (137 mg, 81%). MS: (ESI+) 338.1 was degassed extracted with 10 ml of ethyl acetate twice The combined extracts were washed with 1% aqueous ammonia, water, brine dried over sodium sulfate The solution was concentrated in vacuum the residue purified by flash chromatography eluting with 30% ethyl acetate in hexane
