With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.101861-63-6,4,6-Dichloroindole-2-carboxylic acid,as a common compound, the synthetic route is as follows.
In the reaction bottle,22 g of 4,6-dichloroindolecarboxylic acid was added to 150 mL of DMSO, and then 3 g of copper chloride was added.The reaction was heated at 120 C for 1 h,TLC monitors the reaction of the starting material completely, and the reaction solution is filtered, and then 200 mL of dichloromethane is added to extract the reaction solution three times.The organic phases were combined, washed with 200 mL of water and concentrated.Then in a mixture of acetone and n-hexane (V acetone: V-hexane = 3:1)Recrystallization from 100 mL gives 4,6-dichloroanthracene 14g, 101861-63-6
101861-63-6 4,6-Dichloroindole-2-carboxylic acid 127988, aindole-building-block compound, is more and more widely used in various fields.
