Adding a certain compound to certain chemical reactions, such as: 102359-00-2, name is 2-Oxoindoline-5-carboxylic Acid, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 102359-00-2, Application In Synthesis of 2-Oxoindoline-5-carboxylic Acid
General procedure: To a solution of 4 (1.77 g, 10 mmol) in 120 mL ofdichloromethane and 10 mL of DMF was added 4-methylmorpholine or DIEA (10 mL), TBTU (4.81 g, 15mmol) and aniline derivatives (11 mmol). The mixture wasstirred under room temperature for 18 h and washed in turnwith 5% sodium carbonate solution, 5% citric acid solutionand saturated sodium chloride solution. After dried byanhydrous sodium sulfate, the organic layer was evaporatedto dryness. The residue was purified with flash chromatography(CH2Cl2:CH3OH, 50:1) to afford intermediates 5a-5l, which were used in the next step in short time. To asolution of compounds 5a-5l (1.0 mmol) in 10 mL methanolwas added piperidine (30 muL) and 1H-pyrrole-2-carbaldehyde/furan-2-carbaldehyde (1.0 mmol). The mixturewas stirred at 60 C for 5 h and cooled to room temperature.After kept in fridge overnight, the target compounds 6a-6land 7a-7l were obtained in high yields.
