YieldReaction ConditionsOperation in experiment
47% With copper(l) iodide; triethylamine;bis-triphenylphosphine-palladium(II) chloride; In tetrahydrofuran; at 20℃; for 3.5h; b) 3- (2-Amino-4, 5-dichloro-phenylethynyl)-benzoic acid ethyl ester To a stirring solution of 2-iodo-3, 4-dichloro-aniline (1.2 g, 4.16 MMOL) was added 3-ethynyl-benzoic acid ethyl ester (0.72 g, 4.14 mmol ; LIJIMA, Toru; Endo, YASUYUKI, Tsuji, Motonori; Kawachi, Emico; Kagechika, Hiroyuki; Shudo, Koichi; Chem. Pharm. Bull. 1999, 47 (3), 398-404) in triethylamine (20 mL) and THF (20 mL). To this solution was added copper iodide (7 mg, 0.037 MMOL) and palladium bis (triphenylphosphine) dichloride. The mixture was stirred for 3.5 h at rt. The reaction mixture was concentrated and the crude product was dissolved in EtOAc. The EtOAc solution was washed with saturated, aqueous bicarbonate, H2O, and brine. The EtOAc layer was dried over NA2SO4, filtered, and concentrated. The crude product was subjected to silica gel chromatography (15% EtOAc: Hexane) to afford the title compound, 0.66 g (47%). LCMS 334.2 (M+H).
