In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 35303-76-5 as follows. Safety of 4-(2-Aminoethyl)benzenesulfonamide
DCE (20 mL) in 4- (2-aminoethyl)benzenesulfonamide(110mg, 0.55mmol), AcOH (0.10mL) and tert- butyl 2- (2-formyl -1H-imidazol-1-yl) acetic acid (250mg, 1.19mml) a solution containing the mixturewas stirred for 30 minutes at 80 under nitrogen. The reaction mixture was cooled to 0 , and treated with NaBH (OAc) 3 (3.165g,15mmol). The reaction mixture was stirred at room temperature overnight anddecomposed with water. The reaction mixture was extracted with DCM. The organiclayer was dried and concentrated in vacuo. The residue was purified by flashchromatography on silica gel, tert-butyl 2,2 ‘- (2,2’ – (4-sulfamoyl-phenethylaza screw-yl) bis (methylene) bis (lH-imidazole-2,1 diyl)) resulted diacetate(132mg, 41percent).
According to the analysis of related databases, 35303-76-5, the application of this compound in the production field has become more and more popular.
