Popis:	A series of ten new Schiff base ethers were synthesized by etherification of Schiff base-{4-(pyridine-3-methylimino) methyl phenol} with fatty alkyl bromides of different chain lengths (C 4 -C 18 ) in the presence of base with 80-85% isolated yields. All the synthesized Schiff base ethers (2a-j) were characterized by FT-IR, 1 H NMR, 13 C NMR and Mass spectral studies. Presence of a characteristic peak for ether linkage, C-O at 1039 cm -1 in IR spectra; a triplet around 7.67 ppm in 1 H NMR and a characteristic peak around 69.7 in case of 13 C NMR further confirmed the structures of Schiff base ethers. The structure of all the compounds were further confirmed by their characteristic molecular ion peaks in ESI-MS.
