The compounds were characterised by ir, pmr, 19F nmr, 12C nmr and mass spectral studies. Representative compounds were tested on mice for CNS activities (analgesic and anticonvulsant) and the effects were also observed against amphetamine induced stereotypy on con- ditioned avoidance response and on potentiation of pentobarbitone sodium hypnosis.
