HCID 24386Thionyl ChlorideSolvent

Procedure

A solution of 22.25 g of [p-(p-cyanophenoxy)phenyl]acetic acid in 55 ml of thionyl chloride is refluxed for one hour. The solvent is removed under vacuum, benzene is added (three times) and the solvent removed under vacuum. The residue is dissolved in 135 ml of methanol and stirred at room temperature for 1 hour. The solvent is removed under vacuum to give a gum. The gum is dissolved in 50 ml of warm methanol and the solution is chilled and filtered to give the product, mp 58°-60° C.
