Reaction Steps
bromo-4-methylsulfonyl-2-nitrobenzene (2 g, 7.0 mmol), ethylboronic acid (0.57 g, 7.7 mmol), K2CO3 (3.0 g, 21 mmol), Pd(dppf)Cl2 (0.29 g, 0.35 mmol) in 1,4-dioxane/water (4:1) (24 mL) were heated at 85° C. under N2 overnight. Silica gel chromatography (PE:EA=6:1) gave the title compound (0.66 g, 40%) as a brown solid.
