Reaction Steps

A mixture of 5-mercapto-3-phenyl-1,2,4-oxadiazole (100 parts), potassium carbonate (39 parts), propargyl bromide (66 parts) and dry acetone (500 parts) was heated at reflux for one hour. The solution was cooled, poured into water and extracted with chloroform. The extract was washed and dried and the solvent evaporated off to give 3-phenyl-5-propargylthio-1,2,4-oxadiazole (90 parts, 74% yield), melting point 39.40° C.
