실험 절차

Trifluoroacetic acid (4.08 mL, 53.08 mmol) was added to a solution of tert-butyl 4-(2-(1-acetylindolin-5-yl)ethyl)piperazine-1-carboxylate (0.793 g, 2.12 mmol) in dry DCM and the reaction was stirred at room temperature for 60 min. The mixture was evaporated and the crude mixture was made basic with 10% NaOH aq. The aq phase was extracted with DCM (3×), dried (Na2SO4), filtered and evaporated to give 0.590 g of the product. This product was taken to the next step assuming quantitative yield without further purification. MS (ES+) m/z 274.2 (M+H)+.
