The present invention relates to novel 3-(2-chlor-4-trifluoromethylphenoxy)-1-azetidine carboxamides having the formula: ##STR1## wherein R1 and R2, same or different, are selected from hydrogen, C.sub.1 -C.sub.4 alkyl, and allyl. In a series of 3-(substitutedphenoxy)-1-azetidinecarboxamides, introduction of a chlorine atom at the 2-position of the phenoxy group of the corresponding 4-trifluoromethylphenoxy-1-azetidinecarboxamides resulted in unexpected increased potency in anticonvulsant pharmacological tests.
本发明涉及具有以下结构式的新型3-(2-氯-4-三氟甲基苯氧基)-1-氮杂环戊酰胺:##STR1##其中R1和R2,相同或不同,选自氢、C.sub.1-C.sub.4烷基和烯丙基。在一系列3-(取代苯氧基)-1-氮杂环戊酰胺中,在相应的4-三氟甲基苯氧基-1-氮杂环戊酰胺的苯氧基的2-位引入氯原子导致在抗惊厥药理试验中出现意外增强的效力。
