PdCl2(dppf) (1.79 g, 2.5 mmol) was added and the reaction mixture was heated at 110 C for 6 h. The reaction was cooled to rt and filtered through a pad of celite. The filtrate was removed under reduced pressure and the residue was purified by silica gel column chromatography (0 to 50% EtOAc/hexanes and 1% EtOAc/DCM) to obtain 2-fluoro-4-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (6.2 g, 50% yield) as a tan solid.1H NMR (500 MHz, DMSO-d6): δ 7.12 (d, J = 10.4 Hz, 1H), 6.78 (d, J = 12.8 Hz, 1H), 4.86 (s, 2H), 2.29 (s, 3H), 1.26 (s, 12H); MS (ESI) m/z: 252.2 (M+H+). |
