Procedure
A solution of 3.80 g (19.9 mmol) of 3-(4-cyanophenoxy)propanoic acid in 10 ml of methanol is cooled by an ice bath. 3 ml (40 mmol) of thionyl chloride are added drop by drop and then the reaction medium is agitated with solvent reflux for 2 hours. The reaction mixture is then concentrated under reduced pressure and the evaporation residue is purified by silica column chromatography eluting with the help of a dichloromethane/methanol mixture (99/1; v/v). The expected product is obtained in the form of a white solid with a yield of 79%.
