Synthetic Route of 552330-86-6, These common heterocyclic compound, 552330-86-6, name is 5-Bromoisoindolin-1-one, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: Procedure C: A solution of 4-methyl-7H-pyrrolo[2,3-d]pyrimidine (1, 0.4 g, 3.0 mmol), 5-bromo-2-(4-methoxybenzyl) isoindolin-1-one (2, 1.0 g, 4.5 mmol) and potassium phosphate (1.91 g, 9.0 mmol) in 1, 4-dioxane (15 ml) was degassed with nitrogen for 10 min. Copper (I) iodide (0.28 g, 1.5 mmol) and trans-1, 2-diaminocyclohexane (0.17 g, 1.5 mmol) were added and the reaction was refluxed at 90 C. for 16 h. Progress of the reaction was monitored by TLC. After completion, solvent was removed under reduced pressure. The reaction mixture was diluted with water and extracted twice with ethyl acetate. The organic layer was separated, dried over sodium sulphate, filtered and concentrated under reduced pressure to afford 2-(4-methoxybenzyl)-5-(4-methyl-7H-pyrrolo [2, 3-d] pyrimidin-7-yl) isoindolin-1-one (3) as a yellow solid. Yield: 0.55 g, 47%;
The synthetic route of 552330-86-6 has been constantly updated, and we look forward to future research findings.
