Abstract
The present invention relates to processes for preparing for preparing 3-(methylsulfonyl)propionitrile. The processes comprise the steps of first reacting 2-chloroethyl methyl sulfide with sodium cyanide or potassium cyanide in a solvent or a solvent mixture to form 3-(methylthio)propionitrile, and then reacting the isolated 3-(methylthio)propionitrile with acetic anhydride, acetic acid, and hydrogen peroxide to form 3-(methylsulfonyl)propionitrile.
