Reaction Steps
Ethyl 2-(3-bromo-4-(3-(2-chlorobenzoyl)-5-ethylthiophen-2-yl) [1,2,4]triazol-5-ylmethylcarbamoyl)indole-1-acetate and a 2M aqueous sodium hydroxide solution are added to ethanol, and the mixture is refluxed with stirring for 1 hour. An aqueous citric acid solution is added to adjust the reaction mixture to pH 3 to give 2-(3-bromo-4-(3-(2-chlorobenzoyl)-5-ethylthiophen-2-yl) [1,2,4]triazol-5-ylmethylcarbamoyl)indole-1-acetic acid.
