Application of 1142363-52-7, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 1142363-52-7, name is JNJ-40346527. A new synthetic method of this compound is introduced below.
The salts and solid residues of Compound A were prepared using nine different acidic counter-ions, (wherein the acidic counter-ion is provided by the corresponding acid i.e., sulfuric, phosphoric, methanesulfonic, p-toluenesulfonic, benzenesulfonic, malonic, citric, 1 -malic, and acetic acids), using the following synthetic procedure; Nine samples of Compound A (about 20 mg) prepared as described in Example 1 were added to nine separate 4 mE vials. About 1.1 molar equivalents of the acid (i.e., sulfuric acid, phosphoric acid, methanesulfonic acid, p-toluenesulfonic acid, benzenesulfonic acid, malonic acid, citric acid, 1-malic acid, and acetic acid) solutions (0.1 M in acetone, freshly prepared) was independently added to each vial. The vials were stirred at 500 rpm and heat was applied as necessary. All solutions formed suspensions upon addition of the acid solution to Compound A, with the exception that the acetic acid solution remained a clear mixture. The suspensions were then heated to 40 C. with stirring for about 30 minutes, but no additional clear solutions were observed. Since the solubility of Compound A in acetone is about 130 mg/mE, the formation of a suspension was interpreted as an indication that a salt or other non-free base material (e.g. solvate, co-crystal, etc.) had formed.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1142363-52-7, its application will become more common.
