실험 절차
To a solution of ethyl 4-chloro-1H-pyrrolo[2,3-b]pyridine-5-carboxylate (100 mg) in ethanol (1 mL) was added 1M NaOH solution (0.89 mL) and the mixture was stirred at 50° C. for 2 hours. The mixture was cooled to 4° C. and acidified with 1M HCl and the precipitate was filtrated and washed with water to give 4-chloro-1H-pyrrolo[2,3-b]pyridine-5-carboxylic acid (75 mg) as a white powder.
