실험 절차

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 (23.6 mg, 0.038 mmol) dissolved in toluene (3 mL)/ethanol (0.6 mL)/water (0.4 mL) was added K2CO3 (16 mg, 0.11 mmol), 3,5-dimethylisoxazole-4-boronic acid (11 mg, 0.076 mmol) and tetrakis-(triphenylphosphine)-palladium(0) (9 mg, 0.007 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 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 to afford crude 9-benzhydryloxy-5-(3,5-dimethyl-isoxazol-4-yl)-7-(4-fluoro-benzyl)-6,7-dihydro-pyrrolo[3,4-g]quinolin-8-one 279.
