실험 절차

A mixture of Example 44A (4.0 g, 17.6 mmol), Pd(Ph3P)4 (1.0 g, 0.86 mmol), 4-O-tert-butyldimethylsilyl-phenylboric acid (4.9 g, 23.6 mmol) in toluene (60 mL) and aqueous sodium carbonate (2.76 g dissolved in 25 mL water) was heated to reflux for 12 hours, then cooled to ambient temperature. The mixture was diluted with ethyl acetate (100 mL), washed with water (1×50 mL), dried (Na2SO4), filtered and concentrated under reduced pressure. The residue was stirred in THF (200 mL) containing tetrabutylammonium fluoride (30 mL, 1.0M, 30.0 mmol) for 16 hours. The mixture was diluted with ethyl acetate (100 mL), washed sequentially with water (1×50 mL), aqueous ammonium chloride (1×50 mL), brine (1×50 mL), dried (Na2SO4), filtered and concentrated under reduced pressure to give a solid. The solid was precipitated from ethyl acetate (75 mL), filtered to provide the titled compound as a tan solid (4.27 g, 70%).
