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.

The present patent application relates to an alternative process for the preparation of amino derivatives. In particular, the present application relates to an improved process for the manufacture of Lacosamide (LCM), (R)-2-acetamido-N-benzyl-3-methoxypropion-amide, which is useful as an anticonvulsive drug. In a particular aspect, the present invention relates to a process of manufacture of optically enriched (R)-2-acetamido-N-benzyl-3-methoxypropion-amide (I) comprising resolution of 2-acetamido-N-benzyl-3-methoxypropion-amide (II).

Amino acid amides (AAA) were prepared and evaluated in seizure models. The AAA displayed moderate-to-excellent activity in the maximal electroshock seizure (MES) test and were devoid of activity in the subcutaneous Metrazol-induced (scMet) seizure test. The AAA anticonvulsantactivity was neither strongly influenced by the C(2) substituent nor by the degree of terminal amine substitution. An in vitro
