19% | With potassium acetate;(1,1'-bis(diphenylphosphino)ferrocene)palladium(II) dichloride; In 1,4-dioxane; at 80.0℃; for 21.0h; | A dioxane (16.5 mL) solution of 4-bromo-2,6-difluorobenzoic acid (0.4 g, 1.6 mmol), 4,4,4',4',5,5,5',5'-octamethyl-2,2'-bi(1,3,2-dioxaborolane) (0.5 g, 2.0 mmol), PdCl2(dppf) (0.12 g, 0.17 mmol) and potassium acetate (0.49 g, 4.9 mmol) was placed in a sealed vial and degassed by vacuum-N2 refill cycle twice. The mixture was heated to 80 C. for 21 h, cooled to room temperature and filtered through a short bed of silica gel. The filtrate was concentrated and purified by flash column chromatography (ISCO 12 g silica gel cartridge, 20-100% ethyl acetate-hexanes) to give the expected product as a brown oil (0.11 g, 19%). MS (ES-) m/z: 283 (M-H); LC retention time: 1.48 min (Analytical HPLC Method D). |
