반응 단계
To a reaction vessel was added N-(4-bromobenzyl)biphenyl-4-carboxamide 10-3 (50 mg, 0.14 mmol), 4-methyl-1H-imidazole 11-1 (17 mg, 0.2 mmol), CuI (9 mg, 0.05 mmol), 1,3-di(pyridin-2-yl)propane-1,3-dione (15 mg, 0.07 mmol), Cs2CO3 (89 mg, 0.27 mmol) and DMF (0.7 mL). The reaction was flushed with nitrogen and stirred at 110° C. overnight. After cooling to room temperature, the reaction was diluted into ethyl acetate. The salt was removed by filtration and filtrate was dried. The residue was purified by HPLC to give N-(4-(4-methyl-1H-imidazol-1-yl)benzyl)biphenyl-4-carboxamide 92. MS m/z 368.2 (M+1). 1H NMR 400 MHz (DMSO-d6) δ 9.16 (t, 1H), 8.17 (s, 1H), 8.02 (d, 2H), 7.81 (d, 2H), 7.75 (d, 2H), 7.58 (d, 2H), 7.52-7.40 (m, 6H), 4.54 (d, 2H), 2.17 (s, 3H).
