Versuchsvorschrift

A mixture of 1-[p-(β-butyloxyethyl)-phenyl]-4-(p-bromophenyl)-cyclohexene (XV) (55 g, 0.13 mol) obtained in Step H, chloranil (78.4 g, 0.32 mol) and xylene (624 ml) was heated and placed under reflux for 24 hours. After cooling, toluene (800 ml) was added, insoluble solid filtered off and toluene removed by concentrating the filtrate. The resulting raw crystals were recrystallized from ethyl acetate (50 ml) to obtain 4"-(β-butyloxyethyl)-4-bromoterphenyl (XV1) (29 g) having a melting point of 225.7°~227.0° C.
