실험 절차

Cesium carbonate (119 mg, 0.36 mmol, 1.0 eq) is added at room temperature to a stirred solution of 2-[trans-4-(6-methoxy-3,4-dihydro-2H-1-oxa-4,5,9-triaza-phenanthren-3-yl)-cyclohexyl]-isoindole-1,3-dione (190 mg, 0.36 mmol, 1.0 eq) in N,N-dimethylformamide (3 mL), followed by iodomethane (23 μL, 0.36 mmol, 1.0 eq). After 5 hours stirring at room temperature, one additional equivalent of iodomethane is added to the reaction mixture and, after 2 hours stirring, solvent is removed to give a residue that is extracted with ethyl acetate (3×10 mL) and water (10 mL). The combined organic layers are washed with brine, dried over sodium sulfate, filtered and concentrated to give a residue that is purified by column chromatography (silica gel, eluent: cyclohexane:ethyl acetate:methanol, 1:3:0 to 0:1:0 to 0:9:1, v/v/v) to afford 2-[trans-4-(6-methoxy-4-methyl-3,4-dihydro-2H-1-oxa-4,5,9-triaza-phenanthren-3-yl)-cyclohexyl]-isoindole-1,3-dione as an orange solid (113 mg, 54% yield).
