Adding a certain compound to certain chemical reactions, such as: 2106-02-7, name is 2-Chloro-4-fluoroaniline, belongs to chlorides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 2106-02-7, Product Details of 2106-02-7
[000213] To a stirred solution of crude acid chloride (70 mg, crude) in CH2C12 (5 mL) under argon atmosphere were added 2-chloro-4-fluoroaniline 184 (25 mg, 0.17 mmol) and pyridine (0.07 mL, 0.86 mmol) at 0 C; warmed to RT and stirred for 16 h. The reaction was monitored by TLC; after completion of the reaction, the reaction mixture was diluted with water (20 mL) and extracted with CH2C12 (2 x 30 mL). The combined organic extracts were washed with 1 N HC1 (20 mL), 10% NaHCO3 solution (30 mL), brine (15 mL) dried over sodium sulfate, filtered and concentrated in vacuo to obtain crude. The precipitated material was either directly dried in vacuo or triturated or purified through silica gel column chromatography /preparative HPLC or by acid-base treatment to afford the desired compound.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2-Chloro-4-fluoroaniline, and friends who are interested can also refer to it.
