Adding a certain compound to certain chemical reactions, such as: 1074-82-4, name is Potassium 1,3-dioxoisoindolin-2-ide, 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 1074-82-4, category: indolines-derivatives
To a stirred solution of 1,6-dibromohexane (12.3 mL, 81.0 mmol) in DMF (10 mL), was added potassium phthalate (5.0 g, 27.0 mmol) portion-wise over 30 mm at room temperature. After complete addition, the reaction mixture was stirred at 90 C for 18 h, then quenched with water (300 mL) and extracted with diethyl ether (150 mL x 2). The combined organic extracts were washed with water (100 mL x 2), followed by brine (50 mL x 2) and dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The resultant residue was purified by silica gel column chromatography (60-120 mesh) using 5-10% EtOAc / hexanes to afford 3-i as an off- white solid (6.3 g, 76% yield). LCMS: 310.95 (M+ 1).
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, Potassium 1,3-dioxoisoindolin-2-ide, other downstream synthetic routes, hurry up and to see.
