실험 절차

To a solution of 3-(5-Amino-3H-isobenzofuran-1-ylidene)-1,3-dihydro-indol-2-one (50.0 mg, 0.189 mmol) and N,N-diisopropylethylamine (65.8 μL, 0.378 mmol) in 2.0 mL THF was added iodomethane (12.9 μL, 0.208 mmol). After stirring at room temperature for 21 h, silver triflate (53.4 mg, 0.208 mmol) was added and the mixture heated at 45° C. for 16 h. The mixture was partitioned between EtOAc and saturated NaHCO3 and the organic separated. The organic layer was washed with H2O, brine and then dried with Na2SO4. The solution was evaporated in vacuo and chromatographed with 2% MeOH/CHCl3 to give 3-(5-Dimethylamino-3H-isobenzofuran-1-ylidene)-1,3-dihydro-indol-2-one (1.2 mg) as a yellow-orange solid and 3-(5-Methylamino-3H-isobenzofuran-1-ylidene)-1,3-dihydro-indol-2-one (8.9 mg) as an orange solid.
