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. 102359-00-2, name is 2-Oxoindoline-5-carboxylic Acid belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below. Safety of 2-Oxoindoline-5-carboxylic Acid
264 mg (1.1 mmol) of (S)-2-cyclopropylaminomethyl-pyrrolidine-1-tert-butyl carboxylate is added to a solution of 177 mg (1 mmol) of 2-oxo-2,3-dihydro-1H-indole-5-carboxylic acid (prepared according to the following procedure: Li Sun, Ngoc Tran, Congxin Liang, Flora Tang, Audie Rice, Randall Schreck, Kara Waltz, Laura K. Shawver, Gerald McMahon, and Cho Tang, Journal of Medicinal Chemistry, 1999, Vol. 42, 25, 5120), 417 mg (1.1 mmol) of O-(benzotriazol-1-yl)-N,N,N’,N’-tetramethyluronium, 646 mg (5 mmol) of diisopropylethylamine and 27 mg (0.1 mmol) of 1-hydroxybenzotriazole in 2 ml of dimethylformamide, then the reaction mixture is stirred at room temperature for 30 minutes. The solvent is evaporated, then the product is extracted with ethyl acetate. The organic phases are dried over magnesium sulfate, filtered and evaporated. The residue is purified by chromatography on silica (ethyl acetate/methanol 95/5 then 9/1) to give 254 mg (64%) of (S)-2-{[cyclopropyl-(2-oxo-2,3-dihydro-1H-indole-5-carbonyl)-amino]-methyl}-pyrrolidine-1-tert-butyl carboxylate in the form of a beige solid.
The synthetic route of 102359-00-2 has been constantly updated, and we look forward to future research findings.
