HCID 13076191(4-Fluorophenylthio)acetyl chlorideYield 88%

Procedure

A mixture of 5.3 g of (4-fluorophenylthio)acetic acid and 6.8 g of thionyl chloride is refluxed for 2 hours. Excess of thionyl chloride is evaporated in vacuo and the residue distilled. There are obtained 5.1 g (88%) of oily (4-fluorophenylthio)acetyl chloride, b.p. 76°-77° C./0.25 Torr.
