With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.101774-27-0,6-Bromo-1H-indole-3-carboxylic acid,as a common compound, the synthetic route is as follows.
Step 9; -Bromo-lH-indole-S-carboxylic acid methyl ester; Acetyl chloride (29,43 g, 374 mmol) is added slowly at room temperature to a solution of 6-bromo-indole-3-carboxylic acid (45 g, 187.46 mmol) in 50OmL of methanol and the resulting solution is stirred at 650C overnight. The reaction is cooled to room temperature. A white precipitates appears when cooling. After stirring 2h at room temperature, the solid is filtered off and dried under vacuum. 34.4g (72%) of the title compound is obtained as a light brown solid. MS (m/e): 254 (M+ 1)
101774-27-0, 101774-27-0 6-Bromo-1H-indole-3-carboxylic acid 15284837, aindole-building-block compound, is more and more widely used in various fields.
