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.

A direct synthesis of α‐alkylated arylacetamides from arylacetonitriles and primaryalcohols has been accomplished for the first time. In the presence of the rhodium complex [Rh(cod)Cl]2/triphenylphosphine/potassiumhydroxidesystem, the desired α‐alkylated arylacetamides were obtained in 74–92% yield under microwave conditions. The experimental results in this paper are in sharp contrast with previous
