실험 절차

4.66 mL of 5 N NaOH aqueous was added to a solution of 3.19 g of ethyl 1-cyclopropyl-3-methyl-4-methoxy-1H-indole-6-carboxylate in 32 mL of MeOH and the mixture was stirred at 60° C. overnight. The mixture was cooled and 46.6 mL of 1N HCl was added thereto. The precipitate was filtered, collected and dried in vacuo to afford 2.70 g of 1-Cyclopropyl-3-methyl-4-methoxy-1H-indole-6-carboxylic acid as a colorless solid.
