The synthetic route of 102359-00-2 has been constantly updated, and we look forward to future research findings.

102359-00-2, name is 2-Oxoindoline-5-carboxylic Acid, belongs to indolines-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Computed Properties of C9H7NO3

General procedure: A solution of 9a-d (2 mmol), EDCI (3 mmol) and HOBt (3 mmol) in dry DCM (20 mL) was stirred at 0C for 3.5 h. Then different substituted amines (2.2 mmol) and DIPEA (4 mmol) were added and the reaction was stirred at r.t. for another 1.5 h. The organic layer was washed with water and brine and dried over Na2SO4. Removal of the solvent gave a residue that was purified by column chromatography (silica gel, CH2Cl2-MeOH 100: 1 as an eluent) to furnish 10a-n as white solids.

The synthetic route of 102359-00-2 has been constantly updated, and we look forward to future research findings.
