Procedure

In 15 ml of aqueous ammonia was dissolved 0.39 g of copper iodide, and the solution was added to a solution of 0.33 g of 3,4-dimethoxyphenylacetylene in 20 ml of ethanol at room temperature. The mixture was stirred for 1 hour, filtered, washed five times with water, once with ethanol, and once with ethyl ether, and dried under reduced pressure at 40° C. to yield 110 mg of the title compound.
