Reaction Steps

The crude 1-(4-(2-propyl)phenyl)-2-trimethylsilylacetylene was dissolved in methanol (100 mL). Aqueous 1M potassium carbonate solution (25 mL) was added and the reaction stirred at room temperature for 2 hours. The reaction mixture was then diluted with water and extracted with pentane. The organic layers were combined, dried with magnesium sulfate, and evaporated under reduced pressure without heating to give crude 4-(2-propyl)phenylacetylene.
