Procedure
A solution of 4′-allyloxyacetophenone (6.0 g, 34.1 mmol) in 10 mL xylene is introduced into a thick walled pyrex tube, which is sealed with a teflon cap. After heating to 230° for 5 hours, the solution is cooled to 0°. The precipitated white solid is filtered and the solid is washed with cold toluene and hexane to yield 3′-allyl-4′-hydroxyacetophenone.
