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. 1254319-51-1, name is 6-Bromo-2-methylisoindolin-1-one belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.

6-Bromo-2-raethylisoindolin-l-one (723 mg, 3.41 mmol), bis(pinacolato)diboron (1.04 g, 4.09 mmol), potassium acetate (1.00 g, 10.2 mmol) and PdCl2(dppf) catalyst (139 mg, 0.17 mmol) were weighed into a flask which was sealed under N2. DMSO (15 mL) was added, and the entire mixture stirred at 90C for 5 h. Upon cooling, the reaction mixture was diluted with water (250 mL) and extracted with CH2C12 (5×50 mL). The combined CH2C12 fractions were in turn washed with water (2×100 mL), brine (100 mL), dried (Na2S04), filtered and the solvent removed under reduced pressure to yield the crude product. Purification was carried out by flash column chromatography on silica gel (20% THF/CH2C12 as eluant) to give the title compound as a crystalline beige solid (262 mg, 28%). NMR [400 MHz, (CD3)2SO] delta 7.91 (br s, 1 H), 7.85 (dd, J = 7.6, 1.0 Hz, 1 H), 7.59 (dd, J = 7.5, 0.6 Hz, 1 H), 4.49 (s, 2 H), 3.07 (s, 3 H), 1.32 (s, 12 H). LRMS (APCI+) calcd for Ci5H2iBN03 274 (MH+), found 274.
The synthetic route of 1254319-51-1 has been constantly updated, and we look forward to future research findings.
