Versuchsvorschrift

1-BOC-5-acetoxymethyl-7-nitro-indole-2-carboxylic acid methyl ester (4.7 g, 12.0 mmol) prepared in Step A was dissolved in dichloromethane (50 mL). 2N hydrochloric acid solution (30 mL, 60 mmol) was added thereto, and the mixture was stirred for 12 h at room temperature. The reaction mixture was distilled under reduced pressure to give the solid title compound (3.5 g, Yield 100%).
