Procedure

4-Nitrophenyltrimethylsilylacetylene is reacted at ambient temperature for 3 hours with 3 g of potassium carbonate in 300 ml of methanol. The resulting reaction product mixture is poured into 1500 ml of distilled water to precipitate crude 4-nitrophenylacetylene product. The crude product is separated by filtration, washed with water, and dried in a vacuum oven at 50° C. and 1 Torr.
