実験手順
Alternatively, according to a modified Suzuki coupling method of C. H. Chen; Tetrahedron Letter; EN; 44; 5747-5750; 2003, 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 (266.2 mg, 0.428 mmol) dissolved in toluene (5 mL) was added Na2CO3 (2M in water, 500 μl), 2-methoxypyridine-3-boronic acid (164 mg, 1.07 mmol) and tetrakis-(triphenylphosphine)-palladium(0)(100 mg, 0.086 mmol). The reaction mixture in the flask was flashed with argon three times. It was then heated to 120° C. under argon 4 hours. The reaction was monitored by TLC (EtOAc/hexane 3/7) (Rf1=0.6, Rf17=0.1) 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 (1/1) to afford pure 9-benzhydryloxy-7-(4-fluoro-benzyl)-5-(2-methoxy-pyridin-3-yl)-6,7-dihydro-pyrrolo[3,4-g]quinolin-8-one 288, 125 mg, 50%. 1H NMR (CDCl3) δ 9.0 (dd, 1H), 8.3 (dd, 1H), 8.2 (s, 1H), 7.8 (dd, 4H), 7.7 (dd, 1H), 7.4 (dd, 1H), 7.3-7.1 (m, 8H), 7.0 (m, 2H+1H), 4.7 (dd, 2H), 4.1(dd, 2H), 3.8 (s, 1H); MS: 582 (M+1).
