실험 절차
2-(3-(8-Methoxy-1-oxo-1,2-dihydro-2,7-naphthyridin-3-yl)propyl)isoindoline-1,3-dione (200 mg, 0.55 mmol) is dissolved in CH3CN (2 mL) and POCl3 (59 uL, 0.64 mmol) The mixture is stirred at 80° C. for 3 hours. POCl3 is removed and neutralized with sat. NaHCO3. The compound is extracted with CHCl3 and the organic layer is dried (Na2SO4) and evaporated to yield the crude compound, which is used in the next step without any further purification. MS m/z 382.1 (M+1).
