YieldReaction ConditionsOperation in experiment
90% With n-butyllithium; In tetrahydrofuran; at -78℃; for 1h; The compound <strong>[6287-82-7]2,3-dibromobenzo[b]thiophene</strong> (50.0 g, 171.1 mmole) was mixed with 1000 ml of dry THF. To the mixture, 82.0 ml of N-butyllithium (205.0 mmol) was added at -78 C. and the mixture was stirred for 1 h. After the reaction finished, 32.0 g (240.0 mmol) of Copper(II) Chloride was added and the mixture was stirred 16 h. The solution was extracted with ethyl acetate and water. The organic layer was dried with anhydrous magnesium sulfate and then the solvent was evaporated under reduced pressure. The residue was purified by column chromatography on silica to give product (32.6 g, 90%) as a purple brown solid.
