Versuchsvorschrift

4-t-Butylphenyl 4-methoxyphenyl ketone (862 mg) obtained in Example 29 was dissolved in N,N-dimethylformamide (35 ml), sodium thiomethoxide (562 mg) was added, and the admixture was refluxed for 3 hours under argon. The reaction mixture was partitioned between 10% aqueous phosphoric acid and ethyl acetate. The ethyl acetate layer was then dried with anhydrous magnesium sulfate and the solvent was removed by reduced-pressure distillation to obtain 794 mg of the title compound (yield: 97%).
