Adding a certain compound to certain chemical reactions, such as: 939-80-0, name is 4-Chloro-3-nitrobenzonitrile, 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 939-80-0, COA of Formula: C7H3ClN2O2
General procedure: To a solution of N-hydroxysalicylamide (0.5 g, 3.26 mmol) in anhydrous DMF (5 ml) was added 2a or 2b (3.26 mmol) and freshly calcinated K2CO3 (1.35 g, 9.78 mmol) and the mixture was kept, with stirring at the room temperature overnight. DMF was removed in vacuo and the residue was treated with water (10 ml) and then extracted with CH2Cl2 (5 ml). The organic layer was separated, washed with water, dried over anhydrous CaCl2, and purified by flesh chromatography on silica gel using CH2Cl2 as eluent. Dichloromethane was evaporated in vacuo. The resulting residue was benzo[d]oxazol-2(3H)-one 11. The water layer was acidify by hydrochloric acid, filtered and washed with water. The resulting residue was compound 12a(b).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Chloro-3-nitrobenzonitrile, other downstream synthetic routes, hurry up and to see.
