Phenylacetyl chloride → HCID 10709050, compound

Participants

Reaction Steps

To a solution of 25.0 g of methyl 4-phenylbutyrate in 100 ml of carbon disulfide, 37.3 g of anhydrous aluminium chloride was added and then a solution of 43.3 g of phenylacetyl chloride in 25 ml of carbon disulfide was added dropwise, and the mixture was stirred at room temperature for 3 hours. The reaction mixture was poured into ice-water and extracted with methylene chloride. The methylene chloride layer was washed with aqueous potassium carbonate solution, dried, and then the solvent was removed. The residue was purified by column chromatography on silica gel (methylene chloride:n-hexane=2:1→methylene chloride) to afford 27.3 g of colorless crystals. Recrystallization from isopropyl ether gave colorless flakes, mp 54°~54.5° C.
