Versuchsvorschrift
To a stirred solution of 2.5 g of compound A was added in small portions 1.47 g of powdered aluminum chloride at 130° C. and stirring was continued for another 1 hour. After cooling 1N HCl and chloroform was added to the reaction mixture and the organic layer was separated. The aqueous layer was extracted with chloroform. The combined organic layer was dried over magnesium sulfate and distilled to remove the solvent. The crude product thus obtained was crystallized from hexane to obtain 1.41 g of compound B. Yield: 56.3%.
