Procedure

1 mol of 6-hydroxy-1-tetralone, 1.2 mols of methyl chloroacetate, 2 mols of potassium carbonate and 0.1 mol of potassium iodide are boiled under reflux in 2 l of butanone for 6 hours. The mixture is filtered, the residue is rinsed with acetone and the filtrate is evaporated. The residue is taken up in methylene chloride, and the mixture is washed 3 times with 0.5N NaOH solution, dried over sodium sulphate and evaporated.
