  • Patent number: 4247707
    Abstract: This method of making 5,6-dihydro-2-methyl-N-phenyl-1,4-oxathiin-3-carboxamide is based on the use of an oxathiolane, namely, 2-methyl-N-phenyl-1,3-oxathiolane-2-acetamide, which may be formed by condensing 2-mercaptoethanol with acetoacetanilide under acidic conditions in a solvent medium (aromatic hydrocarbon, chlorinated hydrocarbon or alkyl ester of an aliphatic acid). The said oxathiolane, with or without purification, is reacted with hydrogen peroxide in water or in a water-organic solvent mixture under basic conditions in the presence of a catalytic amount of a metal compound such as sodium tungstate to form 2-methyl-N-phenyl-1,3-oxathiolane-2-acetamide 3-oxide.
