実験手順: A solution of 1,1-dibromo-2-(2,4-dichlorophenyl)ethene (14 g, 42.4 mmol) in THF (100 ml) at −78° C. under nitrogen was treated with butyllithium (1.6 M solution in hexane, 28 ml, 44.8 mmol). after being stirred for 1 hour at −78° C, the reaction mixture was warmed to room temperature and stirred for another hour. The reaction was quenched with water and the product was extracted with hexanes. The extract was dried over MgSO4, filtrated and concentrated in vacuo to give the product. (Corey, E. J.; Fuchs, P. L. Tetrahedron Lett. 1972, 3769) the reaction mixture was warmed to room temperature stirred for another hour The reaction was quenched with water the product was extracted with hexanes The extract was dried over MgSO4 filtrated concentrated in vacuo to give the product
