Procedure

To a solution of 14.7 parts of 2-propene-1-sulfonyl azide in 105 parts of glacial acetic acid containing one part of sodium acetate was added with stirring at room temperature 40% peracetic acid in an amount in excess of that required to convert the propene radical to an epoxypropane radical. The reaction was stirred at room temperature until the peracetic acid content remained constant and then diluted with 200 parts of water and 135 parts of methylene chloride. The methylene chloride layer was removed and washed with water 5 times and then dried over magnesium sulfate. The methylene chloride solvent was removed leaving 15.1 parts of 2,3-epoxypropane-1-sulfonyl azide. The results of an infrared analysis of the product for % azido nitrogen and oxirane oxygen is tabulated below:
