Continuously updated synthesis method about C16H13FN2O3

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. 356068-93-4, name is (Z)-5-((5-Fluoro-2-oxoindolin-3-ylidene)methyl)-2,4-dimethyl-1H-pyrrole-3-carboxylic acid belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below. category: indolines-derivatives

To a stirred solution of compound 109 (0.5 g, 1.67 mmol) in DMF( 40 mL) at O0C was added etaOBt (0.34 g, 2.5 mmol), triethylamine (0.94 mL, 6.68 mmol), ECDI etaC1 (0.48 g, 2.5 mmol) and compound 303 (0.44 g, 2.0 mmol) successively. The mixture was stirred overnight at room temperature, evaporated, diluted with water (50 mL), brine (50 mL) and saturated aqueous sodium bicarbonate(50 mL). The peta of solution was adjusted to 11-12 with 1OM NaOH. The mixture was filtered, washed with water, dried to obtain desired product 304 as a yellow solid (630 mg, 75%). LCMS: 504 [M+l]+, 1H NMR (DMSO-J6): delta 2.39 (s, 3H), 2.41 (s, 3H), 3.59 (m, 2H), 3.69 (s, 3H), 4.15 (t, J= 4.5 Hz, 2H), 6.45 (d, IH), 6.94 (m, 4H), 7.65 (m, 6H), 10.87 (s, IH), 13.66 (s, IH).

The synthetic route of 356068-93-4 has been constantly updated, and we look forward to future research findings.
