YieldReaction ConditionsOperation in experiment
85% 6-Chlorobenzo[b]thiophene (4 g, 23.72 mmol) was dissolved in anhydrous ether (50 mL) in a 250 mL 3-neck round bottom flask with an addition funnel on top under an inert atmosphere. The resulting suspension was cooled to -78C, and sec-BuLi 1.4M (17.79 mL, 24.91 mmol) in cyclohexane was added dropwise over a period of 15 minutes. The reaction mixture was stirred for 60 minutes, keeping the temperature constant. Subsequently, 1,2-dibromo-1,1,2,2-tetrachloroethane (8.11g, 24.91g) was added portion by portion under stirring over a period of 10 minutes. The resulting mixture was slowly warmed to room temperature with stirring for another 16 hours. Subsequently, it was allowed to cool to 0C, and HCl 2N (30 mL) was added dropwise through the addition funnel and stirred for another 30 minutes. The resulting slurry was partitioned between water (100 mL) and ether (100 mL). The organics were separated, and the aqueous phase was back-extracted with ether (100 mL). The combined organic layer was dried over magnesium sulfate and the solvent was removed in vacuo to give an orange oil. The crude mixture was purified by flash chromatography using isohexane as the eluent in a standard silica solid phase to give a yellow oil (5 g, 20.20 mmol, 85%).
