A conventional condensation reaction of an aromatic aldehyde, Benzaldehyde with seven different aromatic amines viz. Aniline, 2-Choro-aniline, 3-Choro-aniline, 4-Choro-aniline, 2-Nitro-aniline, 3-Nitro-aniline and 4-Nitro-aniline and reacted efficiently to synthesize a series of Aldmines, I to VII, in moderate to high yield and high purity. The reaction was monitored and the products were analyzed by employing the TLC technique. All the products obtained were characterized by their colour, physical constant, TLC, elemental analysis and spectral (UV-Vis and FTIR) method. The synthesized Aldimines were subjected to in vitro biological activity.

Compounds containing >C=N- (azomethine) were prepared from Salicylaldehyde with Aniline derivatives by conventional chemical synthesis method. The products are tested in process and the completion of reaction product formation was ascertained by TLC. The final products were characterized by physical viz. m.p., analytical viz. TLC, Instrumental viz. UV-Vis and FTIR spectral techniques. Results showed that all the marked activity coefficients(biopotential) for the studied compounds are less than the standard drug, Ketoconazole.
