PROCEDURE

实验过程

A mixture of 13.02 g of 4-(4-carbo-tert.-butoxyphenyl)-2-methyl-3-butyn-2-ol, 17.97 g of 4-bromo-4'-carbo-tert.-butoxystilbene, 0.93 g of triphenylphosphine. 0.34 g of benzyltriethylammonium chloride, 175 mg of bis(triphenylphosphine)palladium(II) chloride and 175 mg of copper(I) iodide in 70 ml of toluene and 36 ml of 5,5N NaOH is vigorously stirred under reflux for 48 hours. After the addition of 250 ml of saturated ammonium chloride solution, the reaction product is extracted with methylene chloride, dried and concentrated by evaporation.
