With bis-triphenylphosphine-palladium(II) chloride; copper(l) iodide; triethylamine; In N,N-dimethyl-formamide; at 50℃; for 3h; | A solution of 3,5-dichloropicolinonitrile (1.0 eq.), <strong>[39604-97-2]1-ethynyl-4-propoxybenzene</strong> (commercially available) (1.0 eq.), trans-dichlororbis(triphenylphosphine)palladium (II) (10 mol %), copper (I) iodide (20 mol %), and triethylamine (5.0 eq.) in DMF (0.3 M) was stirred at 50 C. for 3 hours. After cooling to ambient temperature, the reaction mixture was diluted with ethyl acetate and 10% aqueous ammonium hydroxide. The two phases were separated, and the aqueous layer was extracted twice with ethyl acetate. The combined organic layers were washed with brine, dried over anhydrous MgSO4, and concentrated en vaccuo. The crude material was purified by flash chromatography on a COMBIFLASH system (ISCO) using 0-10% ethyl acetate in hexane to give 3-chloro-5-((4-propoxyphenyl)ethynyl)picolinonitrile as a white solid. | |
