3-Chloro-4-fluoroaniline 1 on reaction with potassium thiocyanate in glacial acetic acid yielded corresponding thiocyanate derivative 2, which upon oxidative cyclization with bromine in acetic acid yielded 2-amino-5-chloro-6-fluoro[2,1-b][1,3]benzothiazole 3. Compound 3 on reaction with various aromatic aldehydes yielded corresponding aryleneimines 4a-j, which upon reaction with piperazine in the presence of triethylamine gave the title compounds 5a-j. Thus synthesized compounds were characterized compounds by UV, IR, NMR and MASS spectral data. The title compounds were then evaluated for antibacterial, antifungal and anti-inflammatory activities
