The synthesis of new 2(3H )-benzoxazolinonylcarboxamides starting from 2-amino-4,6-dimethylpyridine and 2(3H )-benzoxazolone which were designed as anti-inflammatory agents is described. These derivatives were synthesised from 2(3H )-(benzoxazolinon-6-yl)carboxylic acids, which were obtained by Friedel-Crafts acylation of 2(3H )-benzoxazolone derivatives with oxalyl chloride and acetylchloride in the presence of the AlCl 3 -DMF complex. The constitution of the products was supported by elemental analysis IR and 1 H NMR spectral data.

A novel series of Schiff bases derivatives containing the benzothiazolone moiety have been synthesized in a simple and efficient method, by condensation of 6-amino-2(3H)-benzothiazolone substrates with different aromatic aldehydes, in refluxing ethanol and in the presence of acetic acid as catalyst. The structure of synthesized compounds was elucidated and has been proven using spectral methods such as 1 H NMR, 13 C NMR and elemental analysis. All the newly synthesized compounds were in good agreement with the proposed structures.
