実験手順

This sulfoxide is prepared by reacting, for a week, one equivalent of H2O2 with 4-(2-hydroxyethyl) 3-thiamorpholinone (obtained in Example 9) solubilized at 0° C. in an acetic acid-acetic anhydride mixture. After concentration of the mixture the resulting liquid is solubilized in a minimum of an isopropyl ether-isopropyl alcohol mixture. Starting with this solution, placed at -25° C., white crystals whose melting point is 45° C. are isolated.

後処理
