Procedure

A solution of (RS)-a-hydroxy-(2-methylphenyl)acetic acid (3.6 g) in methanol (80 ml) containing 2 drops of concentrated sulphuric acid was heated at reflux for 2 hours. The reaction mixture was concentrated and the residual oil partitioned between ethyl acetate and water. The organic phase was washed with water, dried over magnesium sulphate and evaporated to give the title compound (2.5 g) as a colourless oil.
