실험 절차

A mixture of 12.65 g of crude (E)-4-bromo-1,1-diethoxy-2-methyl-2-butene, 6.4 ml of m-methoxyphenol, and 8.1 anhydrous potassium carbonate in 100 ml sieve dried dimethylformamide is stirred at room temperature under nitrogen for about 43 hours and the reaction mixture diluted to 500 ml with water and extracted with a 300 ml and two 100 ml portions of hexane. The combined hexane extracts are washed with two portions of brine and dried with sodium sulfate. Concentration of the hexane extracts yields 6.45 g (E)-1,1-diethoxy-(4-m-methoxyphenoxy)-2-methyl-2-butene.
