1,2-Dimethoxyethane → HCID 44481757, compound

Participants

Reaction Steps

A mixture of 2-(3-bromo-1-benzofuran-5-yl)-5-methyl-1,3,4-oxadiazole (251 mg, 0.900 mmol), (4-fluorophenyl)boronic acid (140 mg, 1.00 mmol), tetrakis(triphenylphosphine)palladium(0) (31.2 mg, 0.0270 mmol), sodium carbonate (212 mg, 2.00 mmol), 1,2-dimethoxyethane (5 mL) and water (1 mL) was heated overnight under reflux under an argon atmosphere. After cooling, the reaction mixture was diluted with ethyl acetate, washed with water and saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=1/1) and recrystallized from hexane/ethyl acetate to give the title compound (182 mg, yield 69%) as colorless crystals.
