ABSTRACT:
Benzylidenehydrazono-oxadiazoline compounds have been prepared of the formula: ##STR1## wherein R.sub.1 and R.sub.2 are both lower alkyl or form with the heterocyclic ring carbon atom an alicyclic ring; and R.sub.3 when present is selected from halogen, lower alkyl and lower alkoxy. The preparation involves condensing a benzaldehyde with carbodihydrazide and further condensing with a ketone (or vice versa) to form the corresponding crossed carbodihydrazone, and oxidizing and cyclizing to form the oxadiazoline derivatives. These derivatives have analgesic and/or anti-inflammatory activity.
