실험 절차
N-(2,4-Dimethoxybenzyl)-7-methylquinoxalin-2-amine (0.85 g, 2.75 mmol) was stirred in TFA (10 mL, 130 mmol)/CH2Cl2 (10 mL) at room temperature for 30 min. Solvents were removed on the rotary evaporator. Saturated aqueous NaHCO3 (200 mL) was added to the red residue, which then precipitated a pink solid. The mixture was extracted extensively with DCM. The organic layer was dried over sodium sulfate, concentrated, and dried under vacuum to afford 7-methylquinoxalin-2-amine 2,2,2-trifluoroacetate (640 mg, 2.34 mmol, 85% yield).
