The synthesis of (1S, 2R) -2-fluorocyclopropane amine 4-methylbenzenesulfonate is a crucial research in organic synthesis chemistry. To obtain this compound, there are many ways to go.
First, it can be initiated by a cyclopropane derivative with a specific configuration. First, a suitable cyclopropane raw material is taken, and the fluorine atom is introduced at a specific position through a halogenation reaction to precisely construct the cyclopropane structure containing fluorine. This halogenation reaction requires careful selection of halogenating reagents and reaction conditions, such as the use of specific fluorinating reagents and the reaction in a suitable temperature and solvent environment, to ensure that the fluorine atoms are introduced according to the expected (1S, 2R) configuration.
Then, fluorine-containing cyclopropane is aminated. This step can be achieved by a nucleophilic substitution reaction. Under the catalysis of a suitable base, a suitable amination reagent interacts with fluorocyclopropane to promote the amine group to replace the group at a specific position, thereby forming (1S, 2R) -2-fluorocyclopropane amine. In this process, the type and dosage of bases, as well as the reaction temperature, time and other factors have a huge impact on the yield and selectivity of the reaction, which needs to be carefully regulated.
Furthermore, to obtain (1S, 2R) -2-fluorocyclopropane amine 4-methylbenzenesulfonate, the resulting (1S, 2R) -2-fluorocyclopropane amine needs to be salt-formed with 4-methylbenzenesulfonic acid. In a suitable solvent, mix the two according to the appropriate molar ratio, stir and react for a certain period of time to obtain the target product. After the reaction is completed, it needs to be separated and purified, such as recrystallization, column chromatography and other means, in order to obtain high-purity (1S, 2R) -2-fluorocyclopropane amine 4-methylbenzene sulfonate.
The whole process of synthesis, the control of the reaction conditions, the purification of the intermediate and the maintenance of the configuration are all the keys to the successful preparation of the target compound. The experimenter needs to have exquisite skills and profound chemical knowledge, and careful operation can be achieved.

I don't know what the price range of (1S, 2R) -2 -fluorocyclopropylamine 4 -methylbenzenesulfonate is in the market. This compound may be a rare product, and its price is often determined by many factors.
The raw material is difficult to obtain. If the raw material is rare, difficult to collect, or requires complicated processes to obtain, the cost will be high, and its price will also rise. The simplicity of the preparation process is also the key. If the synthesis process requires multiple steps of reaction, and each step requires precise operation, harsh conditions, and special reagents or instruments are required, the process cost will increase greatly, and the price will not be low.
The supply and demand situation of the market. If there is a large demand for this product, but the supply is scarce, and everyone is competing to buy it, the price will rise; conversely, if the demand is small and the supply is sufficient, the price will be easy to drop. In addition, the number of manufacturers and the competition situation also affect. If there are many manufacturers and the competition is intense, the price may become reasonable; if the manufacturers are less close to monopoly, the price will be very high.
However, because I cannot obtain detailed market information, it is difficult to determine the price range. For details, you can consult the chemical product trading platform, relevant raw material suppliers, or those who specialize in the industry to get a more accurate price range.
