PROCEDURE
实验过程
A mixture of 1,3-dimethyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-one (2.50 g, 10.0 mmol), 2-bromo-1-fluoro-4-methylsulfonylbenzene (2.54 g, 10.0 mmol), CsF (3.8 g, 25.0 mmol), Pd(dppf)Cl2 (0.73 g, 1.0 mmol) in DME (50 mL) and MeOH (25 ml) was stirred at 80° C. for 18 hrs under N2. The mixture was concentrated and the residue was purified by column chromatography on silica gel (PE: EA=2:1-0:1) to give the title compound (1.8 g, 61%) as a red solid. LCMS: 295.9 (M+H)+
