실험 절차

To a round bottom flask were added tert-butyl 2-(6-(5-methoxy-1-methyl-1H-indol-3-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazin-2-yl)hydrazinecarboxylate (0.272 g, 0.505 mmol) and 1,4-dioxane (5 mL). To the mixture was added HCl (4 N in 1,4-dioxane, 1.26 ml, 5.05 mmol) and the reaction mixture was heated to about 60° C. for about 1 h. The reaction mixture was cooled to room temperature and was diluted with EtOAc (50 mL). The solution was washed with saturated aqueous NaHCO3 (50 mL), dried over anhydrous MgSO4, filtered, and concentrated under reduced pressure to give 2-hydrazinyl-6-(5-methoxy-1-methyl-1H-indol-3-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine (0.19 g, 84%): LC/MS (Table 1, Method d) Rt=1.55 min; MS m/z: 439 (M+H)+.
