| Abstract: | A novel synthetic method of 5-{4-2-（5-Ethyl-2-pyridyl）ethoxy]benzyl}-2-imino-4-thiazolidin-one can be got through reduction chloration condensation bromination and cyclization when the 4-2-（5-Ethyl-pyridin-2-yl）-ethoxy]-benzaldehyde was used as raw material.The total yield was achieved to 57%.Comparing to other ordinary methods.this synthetic route had many advantages,such as cheap raw materials,mild reaction conditions,simple opration,and higher yield,especially high toxic methyl acrylate was not used,so it had broad application prospects in industry production. |
