Versuchsvorschrift

Methyl 2,4-dihydroxy-3-(2-propenyl)benzoate (3.0 g) and a few crystals of ammonium chloride were added to 20 ml of pyrrolidine. The reaction mixture was heated to 50° C. and stirred overnight. The reaction mixture was neutralized with 10% hydrochloric acid and extracted with ethyl acetate. Concentration under vacuum to remove solvent gave the product as a light brown solid.
