Adding a certain compound to certain chemical reactions, such as: 6326-79-0, name is 6-Bromoisatin, belongs to indolines-derivatives 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 6326-79-0, Application In Synthesis of 6-Bromoisatin
General procedure: Isatins I (3.0 mmol) was dissolved in anhydrous DMF (15 mL), and the resultant solution was cooled to 0 C (ice bath), whereupon sodium hydride (60% dispersion in mineral oil, 140mg, 3.5 mmol, 1.17 equiv) was added in one portion and stirred for 5 minutes. Iodomethane (497 mg, 3.5 mmol, 1.17 equiv) or benzyl bromide (564.3 mg, 3.3 mmol, 1.1 equiv) was added and the reaction was stirred at 0 C for 30min. The reaction was monitored by TLC until I was fully consumed. The reaction mixture was then poured into saturated aqueous NH4Cl and extracted with ethyl acetate. The combined organic portions were washed with water and brine, dried (MgSO4), filtered, and concentrated to give N-methyl isatins and N-benzyl isatins II (90%-100% yield).
