Reaction Conditions

Reaction Steps

14.07 g (110 mmol) of 2-thiophene-boronic acid, 24.9 g (100 mmol) of 1-iodo-2-nitrobenzene, and 5.78 g (5 mmol) of tetrakis(triphenylphosphine)palladium(0) were dissolved in 250 ml of ethylene glycol dimethyl ether (DME), and 70 ml of 2M K2CO3 aqueous solution was added to the solution, and then the mixture was refluxed at 80° C. for 12 hours. After the reaction was completed, an organic layer was isolated and concentrated, and then isolated by column chromatography using hexane, thereby obtaining 22.1 g (yield: 98%) of 2-(2′-nitrophenyl)-thiophene (A′).
