Versuchsvorschrift
To a stirred solution of t-butyl-4-amino-3-[(2-hydroxy-3-indol-3-yl-N-methylpropanoylamino)methyl]benzoic acid (0.99 g, 2.34 mmole) in CH2Cl2 (20 mL) at RT was added TFA (20 mL). After 12 hr, the reaction contents were evaporated, washed with Et2O and dried under high vacuum overnight affording the title compound (0.86 g, 2.34 mmol) as a pink solid. This product was used without further purification: MS (ES) m/e 369 (M+H-TFA)+.
