Participants

Reaction Steps

To a stirred suspension of 59.2 g. (0.224 mole) of 4-chloro-2-(phenylthio)benzoic acid in 200 ml. of benzene is added dropwise 41.6 g. (0.35 mole) of thionyl chloride during a 1 hour period, and the reaction mixture is heated under reflux for an additional hour. The reaction mixture is then concentrated to dryness under reduced pressure, and the residue is recrystallized from 300 ml. of boiling hexane to yield 41.9 g. of pale yellow product, melting point 94°-96°C.
