実験手順

Cs2CO3 (2.11 g, 6.46 mmol) was added to a solution of 3-bromo-7-methoxyquinolin-2(1H)-one (1.31 g, 5.17 mmol) and 1-text-butyl 2-methyl (2S,4S)-4-{[(4-bromophenyl)sulfonyl]oxy}pyrrolidine-1,2-dicarboxylate (2.0 g, 4.31 mmol) in NMP (21.5 mL), and the reaction mixture was stirred for 40 h at 40° C. An additional portion of 1-tert-butyl 2-methyl (2S,4S)-4-{[(4-bromophenyl)sulfonyl]oxy}pyrrolidine-1,2-dicarboxylate (1.0 g, 2.16 mmol) was added, and the reaction mixture was stirred at 40° C. for 16 h. The reaction mixture was cooled and poured onto a mixture of EtOAc and water, and the layers were separated. The organic layer was washed with water twice, NaHCO3 twice and brine, dried over Mg2SO4, filtered and concentrated. The product was used with no further purification. LRMS (M+H-Boc)+=381.2.
