New anticonvulsant compounds were synthesized and they include the compounds: DL-2-hydroxy-2-(3′,5′-bistrifluoromethylphenyl)butyramide, DL-2-hydroxy-2-(4′-trifluoromethylphenyl)butyramide, DL-2-hydroxy-2-(3′,4′-dichlorophenyl)butyramide, DL-2-hydroxy-2-(3′-bromophenyl)butyramide, DL-2-hydroxy-2-(4′-bromophenyl)butyramide, DL-2-hydroxy-2-(3′-nitrophenyl)butyramide, DL-3-hydroxy-3-(3′,4′-dichlorophenyl)pentanamide, DL-3-hydroxy-3-(4′-bromophenyl)pentanamide, DL-4-hydroxy-4-(3′,4′-dichlorophenyl) hexanamide and DL-4-hydroxy-4-(4′-bromophenyl)hexanamide. They have a significant anticonvulsant activity against pentylenetetrazol-induced seizures as well as unexpected differences in anticonvulsant activity respect those of the non-halogenated compounds. The invention further provides methods for the synthesis of the DL-hydroxy-alkyl-phenyl amides as exemplified in the examples.

Se sintetizaron nuevos anticonvulsionantes entre los que se incluyen los compuestos: DL-2-hidroxi-2-(3',5'- bistrifluorometilfenil) butiramida, DL-2-hidroxi-2-(4'-trifluorometilfenil) butiramida, DL-2-hidroxi-2-(3',4'-diclorofenil) butiramida, DL-2-(3'-bromofenil) bultiramida, DL-2-hidroxi-2-(4'-bromofenil) butiramida, DL-2-hidroxi-2-(3'-nitrofenil) butiramida, DL-3-hidroxi-3-(3',4'-diclorofenil) pentanamida, DL-3-hidroxi-3-(4'-bromofenil) pentanamida, DL-4-hidroxi-4-(3',4'-diclorofenil) hexanamida y DL-4-hidroxi-4-(4'-bromofenil) hexanamida. Los compuestos mencionados presentaron una actividad anticonvulsionante bastante significativa contra las convulsiones producidas por el pentilenotetrazol, así como diferencias inesperadas en la actividad anticonvulsionante con respecto a los compuestos no halogenados. La invención también incluye los métodos para la síntesis de las DL-hidroxi-alquil-fenil amidas tal y como se indica en los ejemplos.
