실험 절차

1,1-Dimethylethyl N-((7-bromo-4-hydroxy-1,1-dimethyl-2-oxo-naphthalene-3-yl)carbonyl)glycinate (250 mg, 0.59 mmol, prepared in Example 53A-E), phenylboronic acid (108 mg, 0.9 mmol), tetrakis(triphenylphosphine)palladium (68 mg, 0.06 mmol), and 2M Na2CO3 (885 μL, 2 mmol) were mixed in dioxane (4 mL). The reaction vessel was placed under an argon atmosphere and stirred at 75° C. for 16 hours. The reaction mixture was cooled to room temperature and partitioned between EtOAc and water. The organic layer was separated, washed with brine, dried (MgSO4), and concentrated in vacuo to give the crude product. The crude product was purified by silica flash chromatography (0-100% DCM/hexane) to give the desired compound as a yellow solid (172 mg). MS (m/e)=366.2 (M+H-tBu)+.
