Procedure

2,5-Dichlorophenol (8 g, 49 mmol) was mixed with potassium carbonate (13.6 g, 98 mmol) and 80% solution of propargyl bromide in toluene (11 ml, 98 mmol) in acetone (100 ml) and stirred overnight at room temperature. The precipitate was removed by filtration and washed with acetone. The acetone solution obtaind was concentrated by rotary evaporation and kept under vacuum for 5 h. The product was obtained as yellow oil with quantitative yield. It was used for futher transformations without additional purification.
