Versuchsvorschrift

A solution was prepared by combining 25.0 g of bis(4-hydroxyphenyl) sulfide, 20.7 g of 2-chloroethyl methyl ether, 31.7 g of potassium carbonate, 3.62 g of potassium iodide, and 50 g of DMF. The solution was aged at 80° C. for 1 week. Under ice cooling, 50 g of water was added to the solution to quench the reaction. To the solution, 50 g of toluene and 50 g of hexane were added. The organic layer was separated and washed with water. On subsequent concentration in vacuum, 28.5 g of the target compound, bis[4-(2-methoxy-ethoxy)phenyl]sulfide was obtained as oily matter. Yield 74%.
