With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.70261-82-4,4-(4-Methylpiperazin-1-ylmethyl)phenylamine,as a common compound, the synthetic route is as follows.
Preparation of 2,4-dihydroxy-5-isopropyl-N-(4-((4-methylpiperazin-l- yl)methyl)phenyl)- benzothioamide (K): [00447] To a stirred solution of 5.0g (21.89mmols) of 2,4-dihydroxy-5- isopropylbenzodithioic acid (J) in 30mL of anhydrous DMF was added 5.9g (70.07mmols) of NaHC03 followed by 2.55g (21.89mmols) of sodium 2-chloroacetate and the mixture was heated at 80 C for lh. 4-((4-methylpiperazin-l-yl)methyl)aniline (4.3g, 20.80mmols) was then added portion wise and the mixture was further heated at 80 C for 2h. The reaction mixture was then cooled, lOOmL of ice-water was added and the pH of the mixture was brought down to approx. 7 using saturated NH4CI solution. The resultant precipitate was then filtered, dried and redissolved in 9:1 ethyl acetate methanol, dried over Na2S04 and concentrated to afford compound K (7.8g) as yellow solid which was carried to next step without purification., 70261-82-4
As the paragraph descriping shows that 70261-82-4 is playing an increasingly important role.
