N,N-Dipropylimidazo[1,2-a]pyridin-5-amine (1.0 g, 4.6 mmol) was diluted in DMF (25 mL). The solution was cooled to 0° C. N-bromosuccinamide (0.83 g, 4.7 mmol) was added. After 5 minutes, the reaction was quenched with water. The solution was extracted with ether, dried, and concentrated. Flash chromatography (40% EtOAc/hexanes) gave the title compound as a yellow oil which solidified upon overnight freezing at −20° C. 0.67 g obtained (49% yield).
