Reaction Steps

To a solution of 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoic acid (200 mg, 0.806 mmol) in CH2Cl2 (10 mL) was subsequently added EDCl (232 mg, 1.21 mmol), HOBt (163 mg, 1.21 mmol), morpholine (0.11 mL, 1.21 mmol), and Et3N (0.22 mL, 1.61 mmol). The mixture was stirred at room temperature overnight, treated with EtOAc/H2O, and extracted with EtOAc. The combined extracts were washed with brine, dried over anhydrous Na2SO4, filtered, and concentrated. The residue was purified by flash chromatography to give the title compound (207 mg, 81% yield). MS (m/z): 318 (M+H)+
