Procedure
A solution of 2-chlorophenylacetic acid (10.0 g) in methanol (100 ml) containing 1 drop of concentrated sulphuric acid was heated at reflux for 2 hours. The reaction mixture was evaporated to half volume and partitioned between ethyl acetate (100 ml) and water (100 ml). The organic phase was dried over magnesium sulphate and evaporated to give the title compound (10.0 g) as a colourless oil.
