Triethylamine → HCID 22710641, compound

Participants

Reaction Steps

In tetrahydrofuran (15 ml) was dissolved 6-bromobenzo[b]thiophene (2.13 g), followed by the addition of triphenylphosphine (787 mg), triethylamine (40 ml), N,N-dimethylformamide (15 ml), trimethylsilylacetylene (1.47 g) and palladium acetate (225 mg). The resulting mixture was refluxed for 5 hours. After the reaction mixture was allowed to cool down, it was diluted with methylene chloride (150 ml). The diluted mixture was washed with water (twice) and saturated aqueous NaCl solution, dried over anhydrous sodium sulfate and distilled under reduced pressure to remove the solvent. The residue was purified by chromatography on a silica gel column (only hexane), whereby the title compound (1.38 g) was obtained.
