To prepare 4- {[4- (diethylamino) phenyl] [4- (diethylamino) cyclohexyl-2,5-diene-1-subunit] methyl} -3 -sulfobenzene sulfonate, the method is as follows:
First take an appropriate amount of 4- (diethylamino) benzaldehyde and 3-sulfonylacetophenone, place in a clean reactor, use anhydrous ethanol as a solvent, add an appropriate amount of catalyst, such as piperidine or pyridine. Under mild heating conditions, maintain an appropriate temperature, such as between 60 and 80 degrees Celsius, and stir to fully react. This reaction is based on the principle of condensation of aldoxone and ketone, and the two substances interact to gradually form an intermediate product. During the
reaction, closely observe the color change and physical state change of the reaction system. When the reaction reaches the expected level, the reaction process can be monitored by thin-layer chromatography or other suitable analytical methods. After the reaction is completed, the reaction solution is cooled to room temperature, and then slowly dropped into an appropriate amount of dilute acid solution, such as dilute hydrochloric acid, to adjust the pH value to a specific range, so that the product precipitates.
The precipitate is separated by suction filtration and washed with cold ethanol for multiple times to remove impurities. Subsequently, the obtained crude product is placed in a suitable organic solvent for recrystallization, such as a mixed solvent of ethanol and water, and the ratio is optimized. The recrystallization process needs to be slowly cooled to allow the crystal to grow regularly and improve the purity of the product.
