    and an NH signal as broad singlet at 11.33 ppm(which disappeared in D 2O exchange) in additionto the disappearance of the signal corresponding

    to the CH 2 group. Moreover, the mass spectrumof this compound showed the molecular ion peakat m/z 357 ([MH] +, 66%), which is in accordancewith its molecular formula. On the other hand,when the thiazolidine deri vatives 2ad were al-lowed to react with the aromatic aldehydes 7ad in the presence of acetic acid in ethanol at reuxtemperature, the cor responding (2 E ,5E )-4-subs-tituted arylidene-2-[( E )-(4-ary lidene)hydrazono]

    thiazolidin-4-ones 8ad were obtained in 78 80%yields. The IR spectra of the disubstituted 2,5-thi-azolidinone derivatives showed the presence of

    characteristic absorption bands at 3325, 1682 and1605 cm 1 corresponding to NH, C=O, and C=N,respectively. The 1H NMR spectrum of compound8a showed signals of the aromatic protons at 6.88 8.05 ppm in addition to an NH signal at 10.55 ppm. The disappearance of the singlet peakof the CH 2 group also conrmed the assignedstructure.
