반응 단계
A mixture of 2-ethyl-7-methylimidazo[4,5-b]pyridine-4-oxide (29.75 g, 0.168 mol), CHCl3 (25 mL) and POCl3 (160 mL) was heated to 80° C. for 1 h. After pouring over ice, the mixture was neutralized by careful addition of NH4OH and extracted with EtOAc. Concentration gave 5-chloro-2-ethyl-7-methylimidazo[4,5-b]pyridine as a solid.
