Reaction Steps

To a mixture of 2-bromo-1-(5-bromo-2-methoxyphenyl)ethanone (500 mg, 1.6 mmol) in EtOH (5 mL), pyridin-2-amine (153 mg, 1.6 mmol) was added. The mixture was stirred at 80° C. for 12 hours, and then cooled to 25° C. After filtrated, the solid was dried in vacuo to provide 2-(5-bromo-2-methoxyphenyl)imidazo[1,2-a]pyridine (30 mg, yield: 5%). 1H-NMR(CDCl3, 400 MHz) δ 8.54 (s, 1H), 8.18 (s, 1H), 8.12˜8.13 (m, 1H), 7.62˜7.64 (m, 1H), 7.37˜7.40 (m, 1H), 7.16˜7.21 (m, 1H), 6.86˜6.88 (m, 1H), 6.76˜6.79 (m, 1H), 3.98 (s, 3H). MS (M+H)+: 303/305.
