Adding a certain compound to certain chemical reactions, such as: 89979-12-4, name is 5-Chloro-2-(methylsulfonamido)benzoic acid, belongs to amides-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 89979-12-4, Formula: C8H8ClNO4S
Mixed 5-chloro-2-(methylsulfonamido)benzoic acid (47mg, 0.187mmol) with HATU (71mg, 0.187mmol) and dissolved in anhydrous DMF (lmL). Stirred for lhr. Dissolved amine hydrogen chloride (49mg, 0.17mmol) in anhydrous DMF (lmL) and added to the reaction. Added TEA (71uL, 0.5 lmmol). Stirred for 16 hrs. Diluted with ethyl acetate and washed with saturated aqueous sodium chloride solution twice. Dried organic extract over anhydrous sodium sulfate and then concentrated under reduced pressure. Purified with silica gel column (0-50% EtOAc in hexanes) to give intermediate 55 (57mg, 39% yield). LC/MS (m/z): 482.2 [M+H]+
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, 5-Chloro-2-(methylsulfonamido)benzoic acid, other downstream synthetic routes, hurry up and to see.
