5381-20-4, Thianaphthene-3-carboxaldehyde is a benzothiophene compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of 5′-chloro-2′-hydroxyacetophenone (50 mg, 0.29 mmol) in ethanol (1.5 mL)50% aqueous potassium hydroxide solution (1.5 mL) and thianaphthene-3-carbaldehyde (57 mg, 0.35 mmol) were added and the mixture was stirred at room temperature.Upon completion of the reaction, the reaction mixture was neutralized with 2N hydrochloric acid.The reaction mixture was extracted with ethyl acetate, and the obtained organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, and then the solvent was distilled off under reduced pressure.The residue was purified by silica gel column chromatography with hexane-methylene chloride (5: 1), methylene chloride and acetic acid effluent solvent,The fractions containing the desired product were collected and the solvent was distilled off under reduced pressure and then recrystallized from methanol. As a result,Compound [4] (14 mg, 0.043 mmol) was obtained as a yellow solid in 15% yield. The results of 1 H NMR and HRMS of the compound [4] are shown below.
5381-20-4 Thianaphthene-3-carboxaldehyde 227328, abenzothiophene compound, is more and more widely used in various.
