실험 절차

To a solution of 6-bromo-1-methyl-1H-benzo[d]imidazole (500 mg, 2.37 mmol) in dioxane (10 mL) was added (3-aminophenyl)boronic acid (320 mg, 2.34 mmol), 2N K2CO3 (2 mL, 4 mmol) and PdCl2(dppf) (50 mg, 0.063 mmol). The reaction mixture was heated at 120° C. under microwave conditions for 30 min. The cooled mixture was concentrated under reduced pressure and the residue dissolved in ethyl acetate, washed with water with the separated organic layers being dried and concentrated to afford the desired product as a brown solid (300 mg, 56.7%). LCMS (m/z): 224.1 [M+H]+
