What are the preparation methods of Toluene-4-Sulfonic Acid 3- (2-Ethoxy-5-Methylphenyl) -3-Phenyl-Propylester?
There are various ways to prepare toluene-4-sulfonic acid-3- (2-ethoxy-5-methylphenyl) -3-phenylpropyl ester, which are described in detail as follows:
First, it can be prepared by esterification reaction. Take 3- (2-ethoxy-5-methylphenyl) -3-phenyl-1-propanol and toluene-4-sulfonic acid with suitable catalysts, such as p-toluenesulfonic acid itself, or strong acids such as sulfuric acid, in appropriate reaction solvents, such as toluene, dichloromethane, etc., and heat and reflux. In this process, the hydroxyl group of the alcohol and the carboxyl group of the sulfonic acid are esterified and dehydrated to form the target product. When reacting, it is necessary to pay attention to the control of temperature. If it is too high, it is easy to cause side reactions, and if it is too low, the reaction rate will be delayed. Generally speaking, the temperature can be set between 80 and 120 ° C, depending on the boiling point of the solvent and the activity of the reactants. The reaction process can be monitored by thin layer chromatography (TLC). When the raw material point almost disappears, the reaction tends to be complete. Afterwards, after neutralization, extraction, drying, column chromatography and other post-processing steps, a pure product can be obtained.
Second, the acid chloride method can also be used. First, toluene-4-sulfonic acid is converted into toluene-4-sulfonyl chloride, which is often interacted with chlorinated reagents such as thionyl chloride and phosphorus trichloride. The resulting sulfonyl chloride has high activity and can react with 3- (2-ethoxy-5-methylphenyl) -3-phenyl-1-propanol in the presence of a base. Bases can be selected from triethylamine, pyridine, etc., which can neutralize the hydrogen chloride generated by the reaction and promote the forward reaction. The reaction usually starts at a low temperature, such as 0-5 ° C, and then gradually rises to room temperature to facilitate the complete reaction. This approach has high reactivity and fast rate, but the chlorination reagent is corrosive, the operation needs to be cautious, and the post-reaction treatment also needs to be meticulous to prevent product loss and impurity residue.
Third, it can also be prepared by transesterification method. If there are suitable toluene-4-sulfonate esters, such as methyl esters, ethyl esters, etc., it can be transesterified with 3- (2-ethoxy-5-methylphenyl) -3-phenyl-1-propanol under the action of catalysts. The catalysts can be organotin compounds, titanates, etc. Under high temperature and reduced pressure, it is easier to remove the generated small molecule alcohol, promote the right shift of equilibrium, and improve the yield of the product. However, this method requires a higher degree of vacuum and temperature for the reaction equipment.
