Extracurricular laboratory: Synthetic route of 1074-82-4

Statistics shows that 1074-82-4 is playing an increasingly important role. we look forward to future research findings about Potassium 1,3-dioxoisoindolin-2-ide.

1074-82-4, name is Potassium 1,3-dioxoisoindolin-2-ide, belongs to indolines-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. 1074-82-4

2-(6-bromohexyl)isoindoline-1,3-dione (10). To a stirred solution of 1,6-dibromohexane (9) (16.5 g, 67.5 mmol) in acetone (100 mL) was added potassium phthalimide (5.00 g, 27.0 mmol). The resulting mixture was refluxed for 24 hours. The reaction mixture was cooled to room temperature and the solvent was removed in vacuo. MPLC purification of the residue (Hexanes:EtOAc/70:30) gave 10 as a colorless oily liquid (6.3 g, 75%). 1H NMR (400 MHz, CDCl3) delta 7.85-7.83 (m, 2H), 7.72-7.70 (m, 2H), 3.68 (t, J=7.2 Hz, 2H), 3.39 (t, J=6.8 Hz, 2H), 1.89-1.82 (m, 2H), 1.73-1.66 (m, 2H), 1.52-1.45 (m, 2H), and 1.41-1.33 (m, 2H).

Statistics shows that 1074-82-4 is playing an increasingly important role. we look forward to future research findings about Potassium 1,3-dioxoisoindolin-2-ide.
