To prepare (4Z, 4'E) -N, N '- (2,5-dioxybenzene-1,4-diyl) bis (4- {[2-oxo-5- (triethoxyformyl) phenyl] sulfur} -3-oxo-3,4-dioxythiophene-2-yl) acetamide, the method is as follows:
First take an appropriate amount of 2,5-dioxybenzene-1,4-diamine, place it in a clean reaction vessel, add an appropriate amount of organic solvent, such as dichloromethane or N, N-dimethylformamide, to fully dissolve and form a uniform solution.
Another thiophene derivative containing a specific substituent, namely 4- {[2-oxo-5- (triethoxycarboxyl) phenyl] sulfur} -3-oxo-3,4-dioxythiophene-2-ylacetyl halide, is also dissolved in a suitable organic solvent. The preparation of this halide requires a multi-step reaction. First, 2-oxo-5- (triethoxycarboxyl) benzoic acid is used as the starting material, converted into the corresponding acyl halide by the action of a halogenating agent, and then reacted with the sulfur-containing thiophene derivative to introduce the sulfur atom and the desired substituent.
The above two solutions are slowly mixed under low temperature and stirring conditions. The purpose of low temperature is to control the reaction rate and avoid the occurrence of side reactions. An ice bath or low-temperature coolant can be used to maintain a suitable temperature of about 0-5 ° C.
During the reaction process, closely monitor the reaction process. The reaction mixture can be developed with a specific development agent by thin layer chromatography (TLC), observe the change of the raw material point and the product point, and determine whether the reaction is complete.
After the reaction is completed, pour the reaction liquid into an appropriate amount of ice water to precipitate the product. At this time, the product often exists in solid form and can be collected by filtration. The collected solid product is washed in sequence with an appropriate amount of water and an organic solvent to remove residual impurities.
