Abstract
The present invention provides an industrially-preferable method for safely producing N-benzyl-2-bromo-3-methoxypropionamide at a high yield but at low cost. The method for producing of the present invention includes: in sequence, an amidation process that causes diacrylic anhydride to react with benzylamine in a solvent to obtain N-benzylacrylamide; a bromination process that causes N-benzylacrylamide to react with bromine in a solvent to obtain N-benzyl-2,3-dibromopropionamide; and a methoxylation process that causes N-benzyl-2,3-dibromopropionamide to react with methanol in the presence of a base to obtain N-benzyl-2-bromo-3-methoxypropionamide.
