1,2-Dimethoxyethane → HCID 57835212, compound

Participants

Reaction Steps

In a dry round bottom flask were added 2-fluoro-6-iodobenzonitrile (500 mg; 2.02 mmol), 3-thiophene boronic acid (311 mg; 2.43 mmol), sodium carbonate (2.32 g; 21.86 mmol), tetrakis(triphenylphosphine)palladium(0) (77 mg; 0.07 mmol), DME (20 mL) and water (20 mL) and heated to reflux for 5 hours. The reaction mixture was cooled to room temperature and extracted with ethyl acetate (3×), washed with brine (1×) and water (1×). Organic layers were combined and dried over sodium sulfate and then filtered and solvent removed to yield crude material which was purified by column chromatography (4% ethyl acetate/hexane) to obtain 150 milligrams of 2-fluoro-6-thiophen-3-yl-benzonitrile.
