실험 절차

1-tert-Butyl 2-ethyl 7-[cyclopropyl(pyridin-2-ylsulfonyl)amino]-5-(2-methoxyethoxy)indoline-1,2-dicarboxylate (1.70 g) was added to 4N hydogen chloride-ethyl acetate solution (50 mL), and the mixture was stirred at room temperature for 2 hr. The reaction mixture was concentrated under reduced pressure, and the residue was diluted with ethyl acetate and aqueous sodium bicarbonate solution. The organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, and filtered, and the filtrate was concentrated under reduced pressure to give the title compound (1.34 g, yield 96%) as a pale-yellow amorphous solid.
