실험 절차

The mixture of rac-3-bromo-6-chloro-3-(3-chloro-benzyl)-1,3-dihydro-indol-2-one (200 mg, 0.55 mmol) (from example 1c supra), 6-Chloro-3,4-dihydro-1H-quinoxalin-2-one (100 mg, 0.55 mmol) and K2CO3 (150 mg, 1.09 mmol) in acetonitrile (3 mL) was stirred at room temperature for 2 hour. The mixture was concentrated in vacuo and purified by flash column chromatography to give 110 mg 6-Chloro-4-[6-chloro-3-(3-chloro-benzyl)-2-oxo-2,3-dihydro-1H-indol-3-yl]-3,4-dihydro-1H-quinoxalin-2-one. MS: [M+H]+=472.
