| Abstract: | Using inexpensive and readily available o-hydroxybenzaldehyde, primary amine and bromoethane, o-ethoxybenzaldehyde was synthesized by simple two-step reactions under mild conditions. Through screen experiments, optimum technological condition of synthesis was estab-lished. Comparing to the reported methods, the good yield was achieved up to 83%. The struc-ture of product was characterized through 1 H NMR, 13 C NMR spectra and elemental analysis and the result is consistent with target compound. |
