With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.39689-58-2,2-(1H-Indol-6-yl)acetic acid,as a common compound, the synthetic route is as follows.
39689-58-2, General procedure: to a solution of the substituted acid in DMF (0.25 mmol/mL) were added DMAP (2 to 4 equiv), EDCI.HCI (1 to 1.5 equiv) and the substituted amine (1 equiv). The reaction mixture was stirred at rt. After completion of the reaction (monitored by TLC), sat. NH4CI or HCI 0.5N was added and the solution was extracted with EtOAc. The organic layer was washed with sat. NH4CI, dried over Mg504, filtered and evaporated to dryness underreduced pressure (Figure 3AA).
As the paragraph descriping shows that 39689-58-2 is playing an increasingly important role.
