Synthesis of 1-phenyl-2-(phenylcarbamoyl)pyrazolidines as potential anticonvulsant agents

Twelve 1-phenyl-2-(phenylcarbamoyl)pyrazolidines were synthesized from 1-arylpyrazolidines and aryl isocyanates. These adducts showed little anticonvulsant activity in the maximal electroshock seizure and pentylenetetrazol seizure assays.
