Page/Page column 24, (2012/06/01)
The present invention provides a process for the preparation of lacosamide in substantially optically pure form, which in one aspect comprises the following steps: (i) resolution of O-methyl-D,L-serine to provide O-methyl-D-serine in substantially optically pure form; (ii) acetylation of O-methyl-D-serine thereby obtained to provide the N-acetyl 10 derivative thereof in substantially optically pure form; (iii) activating the carboxy group of the compound thereby obtained; and (iv) reacting the compound thereby obtained with benzylamine.

The structure-activity relationship (SAR) for the N-benzyl group in the clinical antiepileptic agent (R)-lacosamide [(R)-N-benzyl 2-acetamido-3- methoxypropionamide, (R)-3] has been explored. Forty-three compounds were prepared and then evaluated at the National Institute of Neurological Disorders and Stroke Anticonvulsant Screening Program for seizure protection in the maximal electroshock (MES) and subcutaneous Metrazol models. Comparing activities for two series of substituted aryl regioisomers (2′, 3′, 4′) showed that 4′-modified derivatives had the highest activity. Significantly, structural latitude existed at the 4′-site. The SAR indicated that nonbulky 4′-substituted (R)-3 derivatives exhibited superb activity, independent of their electronic properties. Activities in the MES test of several compounds were comparable with or exceeded that of (R)-3 and surpassed the activities observed for the traditional antiepileptic agents phenytoin, phenobarbital, and valproate. 2009 American Chemical Society.
