Versuchsvorschrift
To a 1 L flask containing a solution of 1-bromo-4-[(Z) -2-chloro-2-(4-butyl-phenyl) vinyl] benzene (VIe) (100 g; 0.285 mol) in 1,4-dioxane (500 mL; 5 vols) and MeOH (200 mL; 2vols), KOH (32 g; 0.571 mol) was added in one portion. Protocol and work-up was then similar with those described above. Title compound (m=80 g) was obtained in a 89% yield. Melting point: 75.6-76.1° C.
