実験手順

To a solution of trifluoro-methanesulfonic acid 9-benzhydryloxy-7-(4-fluoro-benzyl)-8-oxo-7,8-dihydro-6H-pyrrolo[3,4-g]quinolin-5-yl ester 46 (33.5 mg, 0.05 mmol) dissolved in toluene (3 mL)/ethanol (0.6 mL)/water (0.4 mL) was added K2CO3 (22 mg, 0.15 mmol), (2-ethoxycarbonylphenyl)boronic acid (22 mg, 0.10 mmol) and tetrakis-(triphenylphosphine)-palladium(0)(12.5 mg, 0.01 mmol). The reaction mixture in the flask was flashed with argon three times. It was then heated to 120° C. under argon 3 hours. The reaction was monitored by TLC (EtOAc/hexane 3/7) (Rf 46=0.6, Rf 281=0.5) and LC/MS. After cooling to room temperature, the mixture was diluted with EtOAc (20 mL) and washed with 1N HCl, saturated NaHCO3 and brine. The organic phase was dried (MgSO4), filtered and concentrated in vacuo. The residue was purified by flash chromatography on silica gel with EtOAc/Hexane (3/7) to afford pure 2-[9-benzhydryloxy-7-(4-fluoro-benzyl)-8-oxo-7,8-dihydro-6H-pyrrolo[3,4-g]quinolin-5-yl]-benzoic acid ethyl ester 281, 9 mg, 26.8%.
