실험 절차

A mixture of 5-tert-butoxycarbonylmethoxy-1H-indole-2-carboxylic acid ethyl ester (2 g, 6 mmol) and trifluoroacetic acid (8 mL) in dichloromethane (8 mL) was stirred at room temperature for 2 hours. The reaction was concentrated to give 1.6 g (97%) of 5-carboxymethoxy-1H-indole-2-carboxylic acid ethyl ester as a light brown solid.
