Hydrochloric Acid → HCID 23154554, compound

Participants

Reaction Steps

To a solution of 5-bromobenzothiophene (1 g) and phenylacetyl chloride (1.1 g) in dichloromethane (50 mL) was added aluminum chloride (1.9 g) at 0° C. and the mixture was stirred at the same temperature for 2 hours. The reaction mixture was poured into an ice-cooled hydrochloric acid aqueous solution (2 mol/L) and the mixture was extracted with diethyl ether. The organic layer washed with water and brine and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel (eluent: n-hexane/ethyl acetate=8/1). After the solvent was removed, the residual solid washed with hexane to give the title compound (1.1 g).
