Synthesis and anxiolytic activity of N-substituted cyclic imides N-[4-[(4-aryl)-1-piperazinyl]alkyl]-5,7-dioxabicyclo[2.2.2]octane-2, 3-dicarboximide.

The preparation of N-substituted cyclic imides N-[4-[(4-aryl)-1-piperazinyl]alkyl]-5,7-dioxabicyclo[2.2.2]octane- 2, 3-dicarboximides by condensation of N-(3-chloropropyl)- or N-(4-chlorobutyl)imides with appropriate amine has been described. One of compounds was tested in the Vogel's test and displayed an expected activity on CNS.
