50 g of diphenylphosphine were mixed with 150 ml of ethanol under nitrogen atmosphere. 37.12 g of potassium carbonate were then added to the mixture and the mixture was stirred. Finally, 125.73 g of ethyl iodide were added dropwise. After 48 hours at 50° C., the ethanol was removed. The product was then dissolved in chloroform.
