To a solution of methyl 3-[(2S)-2-methylpyrrolidin-1-yl]-2-[1-[tris(propan-2-yl)silyl]-1H-pyrrol-3-yl]quinoxaline-6-carboxylate (150 mg, 0.30 mmol) in tetrahydrofuran (30 ml) was added Tetra-n-butylammonium fluoride (TBAF) (80 mg, 0.31 mmol) with stirring for 10 min at room temperature. The reaction was then quenched with water (10 ml). The resulting solution was extracted with dichloromethane (3×10 ml) and the organic layers combined and dried over anhydrous magnesium sulfate, concentrated under vacuum to afford methyl 3-[(2S)-2-methylpyrrolidin-1-yl]-2-(1H-pyrrol-3-yl)quinoxaline-6-carboxylate as a light yellow solid (100 mg, 98%).
