Reaction Steps
A stirred mixture of 1-(2-bromophenyl)-2-phenylethan-1-ol (15.50 g) and orthophosphoric acid (150 ml) was heated at 170° C. for 1 hour and then poured into iced water and extracted with ether. The extracts were washed with water, dried and concentrated to give the crude product as an orange oil (14.29 g). Evaporative distillation (0.3 torr; oven temperature 140° C.) gave E-1-phenyl-2(2-bromophenyl)ethylene (12.53 g, 86% yield) as a pale yellow oil with a purity of 97% by GC.
