Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 102359-00-2, name is 2-Oxoindoline-5-carboxylic Acid, A new synthetic method of this compound is introduced below., Application In Synthesis of 2-Oxoindoline-5-carboxylic Acid
To a stirred solution of 2-oxoindoline-5-carboxylic acid (0.7 g, 3.95 mmol) in DMF (5 mL) was added EDCI.HCl (1.13 g, 5.92 mmol), HOBt (0.8 g, 5.92 mmol) and triethylamine (1.7 mL, 11.8 mmol). The solution was stirred for 10 min at 0oC. After that tert-butyl 4-(aminomethyl)piperidine-1-carboxylate (0.93 g, 4.34 mmol) was added and the reaction stirred at rt for 16 h. The progress of the reaction was monitored by TLC. After complete consumption of starting material, the reaction was quenched with water and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous Na2SO4and concentrated under reduced pressure to obtain a crude residue which was purified by preparative HPLC to afford tert-butyl 4-((2-oxoindoline-5- carboxamido)methyl)piperidine-1-carboxylate (0.130 g, 8%)
The synthetic route of 102359-00-2 has been constantly updated, and we look forward to future research findings.
