Procedure

A mixture of 28.5 g 3-methoxy-4-(hydroxy)benzoic acid methyl ester, 25.94 g Of finely powdered potassium carbonate, 0.070 g potassium iodide and 285 ml of 2-butanone is heated at reflux temperature for 41 hours. The reaction is cooled and filtered. The filtrate is concentrated in vacuo and recrystallized from hexane to give 40.8 g of the desired product as white crystals.
