Tetrahydrofuran → HCID 608124, compound

Participants

Reaction Steps

To a mixture of ethyl 3-(2-acetamidoethyl)-5-methoxy-1H-indole-2-carboxylate (350 mg), tetrahydrofuran (5.00 mL), and ethanol (5.00 mL) was added a 1 M aqueous sodium hydroxide solution (2.00 mL), followed by stirring at room temperature for 1 hour. The solvent was evaporated under reduced pressure, and the obtained residue was dissolved in water and adjusted to be weakly acidic by the addition of 1 M hydrochloric acid. The precipitated solid was collected by filtration and then dried to obtain 3-(2-acetamidoethyl)-5-methoxy-1H-indole-2-carboxylic acid (300 mg) as a gray solid.
