Introduction of a new synthetic route about 138-41-0

The chemical industry reduces the impact on the environment during synthesis Carzenide. I believe this compound will play a more active role in future production and life.

Synthetic Route of 138-41-0, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 138-41-0, name is Carzenide, This compound has unique chemical properties. The synthetic route is as follows.

. To a stirred suspension of 4- [SULFAMOYL-BENZOIC] acid (25.0 g, 0.124 mol) in 4: 1 CH2CI2/MeOH at rt was added 1.0 M TMSCHN2 in hexane (175 mL), and the reaction mixture was allowed to stir for 2 h. The mixture was diluted with 1 N [NAOH] (100 mL) and CH2CI2 (150 mL), and the layers were separated. The organic layer was dried over [NA2SO4,] then filtered, and the solvent was removed under reduced pressure to afford the desired ester (25.2 g, 95%), which was used without further purification. 1H NMR (400 MHz, DMSO-d6) : 8.14 (d, J = 8.1 Hz, 2H), 7.96 (d, J = 8.1 Hz, 2H), 7.58 (s, 2H), 3.90 (s, 3H).

The chemical industry reduces the impact on the environment during synthesis Carzenide. I believe this compound will play a more active role in future production and life.

A new synthetic route of 138-41-0

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.

Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 138-41-0, name is Carzenide, A new synthetic method of this compound is introduced below., COA of Formula: C7H7NO4S

Pathway ii: A mixture of 4-(aminosulfonyl)benzoic acid (4)(2 mmol) and N,N,N,N-tetramethyl-O-(1H-benzotriazol-1-yl)uraniumhexafluorophosphate (HBTU) (2 mmol) in DMF(2 mL) was stirred at room temperature for 1 h. Then, a solution of the appropriate amine derivative (2 mmol) in TEA (2 mmol) was added dropwise. The reaction mixture was left overnight and then quenched with water (10 mL) and extracted with EtOAc (3 5 mL).The organic phase was dried with Na2SO4 and the solvent was removed in vacuo. The residue was purified by flash chromatography(DCM/MeOH 96:4), crystallized by treatment with a mixtureof Et2O and EtOH (1:1) to give the desired final compounds 5b, 5c,6a, 7a-f and 8a-d as white crystals. For compounds 5 a-d, 6a, 8a and 8d registered CAS numbers have been already assigned. However,their synthetic procedures, chemical properties and structural characterization are not available in literature.

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
