In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 552330-86-6, name is 5-Bromoisoindolin-1-one belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below. Product Details of 552330-86-6
Step A: 5-Bromo-1-oxo-1,3-dihydro-isoindole-2-carboxylic acid tert-butyl ester To a solution of 5-bromo-2,3-dihydro-isoindol-1-one (10.0 g, 47.4 mmol) in THF (100 mL) was added a solution of (Boc)2O (20.6 g, 94.5 mmol), and DMAP (0.57 g, 4.6 mmol). The reaction mixture was stirred at ambient temp overnight. Upon completion, the reaction mixture was concentrated in vacuo, and the residue was purified by flash column chromatography (EA:PE=1:10) to afford the title compound (13 g, 88%).
The synthetic route of 552330-86-6 has been constantly updated, and we look forward to future research findings.
