Dimethylformamide → HCID 21990156, compound

Participants

Reaction Steps

In 7.0 mL of methylene chloride was dissolved 1.40 g of 3-[2-(1-benzothiophen-4-yl)ethoxy]-1-propanol, followed by adding thereto 1.10 mL of thionyl chloride and 0.05 mL of N,N-dimethylformamide, and the resulting mixture was heated under reflux for 5 hours. Then, the solvent was distilled off under reduced pressure. The residue was purified by a column chromatography (eluent; hexane:ethyl acetate=20:1) to obtain 1.43 g of 4-[2-(3-chloropropoxy)ethyl]-1-benzothiophene as a yellow oil.
