実験手順
1-[4-(2-benzyloxyethoxy)phenyl]-1,2-bis-(4-benzyloxyphenyl)-4-chloro-but-1-ene was prepared from 4-[4-(2-benzyloxyethoxy)phenyl]-3,4-bis-(4-benzyloxyphenyl)-but-3-en-1-ol (0.65 g, 0.98 mmol),triphenyl phosphine (0.5 g, 1.96 mmol) and carbon tetrachloride (0.74 g, 4.9 mmol) by the method described in example 2. The product was purified by flash chromatography (toluene). Yield 0.42 g.
