An improved synthesis of Lacosamide 1 with high purity has been developed. Critical parameters of each step were identified as well as the impurities generated. Moreover, a creative method to improve chiral purity and stability of the key intermediate (R)-2-amino-N-benzyl-3-methoxypropionamide 10 by forming salt with an achiral acid (phosphoric acid) was discovered to ensure the chiral purity of (R)-Lacosamide. Phosphoric acid was further developed for the deprotection of the Boc group.

The invention relates to an industrial preparation method of lacosamide. Esterification is performed on D-serine for generating D-serine methyl ester hydrochloride; the D-serine methyl ester hydrochloride reacts with acetyl chloride for generating N-acetyl-D-serine methyl ester; the N-acetyl-D-serine methyl ester reacts with benzylamine for obtaining (R)-2-acetamido-N-benzyl-3-hydroxypropionamide;the (R)-2-acetamido-N-benzyl-3-hydroxypropionamide reacts with methyl p-toluenesulfonate under an alkaline condition for obtaining (R)-2-acetamido-N-benzyl-3-methoxypropionamide. The preparation method provide by the invention has relatively mild reaction conditions in each steps; the raw materials are easy to obtain; no high-toxicity reagent is used; a safe and environment-friendly green chemistry idea is met; and the method is suitable for industrial amplification.
