Versuchsvorschrift
A mixture of α,α'-dichloroxylene (8.75 g, 50 mmol) and potassium phthalimide (5.6 g, 30 mmol) was heated to 50° C. for 24 h. Then the reaction mixture was concentrated in vacuo, dissolved in ethyl acetate and, after usual work-up, the desired compound was obtained by flash chromatography on silica gel (ethyl acetate:hexane; 15:85) (6 g, 65%).
