반응 단계
A mixture of 2-boronobenzoic acid (400 mg, 2.4 mmol), 2-bromopyridine (416 mg, 2.6 mmol), K2CO3 (994 mg, 7.2 mmol) and Pd(dppf)Cl2 (20 mg) in dioxane (8 mL) and H2O (2 mL) was stirred at 125° C. for 30 min. under microwave heating under N2. The catalyst was filtered, and the filtrate was acidified with 2N HCl to pH 5˜6. The solution was concentrated, and the residue was dissolved in MeOH and filtered. The filtrate was concentrated, and the residue was purified by prep-TLC to give the title compound (205 mg, Yield 42.9%). LCMS (m/z): 200.0 (M+1).
