Simple exploration of 5922-60-1

At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2-Amino-5-chlorobenzonitrile, and friends who are interested can also refer to it.

Adding a certain compound to certain chemical reactions, such as: 5922-60-1, name is 2-Amino-5-chlorobenzonitrile, belongs to nitriles-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 5922-60-1, Formula: C7H5ClN2

To the stirred solution of 2-amino-5-chloro-benzonitrile (500 mg, 3.28 mmol) in diethyl ether (10 ml) was added 3-chloro phenyl magnesium bromide (freshly prepared 1M solution in ether, 10 ml, 9.83 mmol) drop wise at 0¡ãC and the resulting reaction mixture was refluxed for 1 h. Then the mixture was stirred for 16 h at 25¡ãC, cooled to 5¡ãC and quenched with water followed by 2 N HC1 solution (20 ml). The reaction mixture was stirred at 45¡ãC for 5 h and then the pH of the reaction mixture was adjusted to 8-9 with 2N aqueous NaOH solution. The mixture was extracted with diethyl ether (3×30 ml) and the combined organic extracts were washed with brine (25 ml), dried over sodium sulfate and concentrated in vacuo to give a crude residue which was purified by flash column chromatography (5percent ethyl acetate in hexane) to yield (2-amino-5-chloro-phenyl)-(3- chloro-phenyl)-methanone (550 mg, 63percent) as a yellow solid. LC-MS (ESI): 266 (M+H)+.
