Reaction Conditions

Reaction Steps

In a nitrogen atmosphere, 17.33 g (70 mmol) of 5-chloro-2-methylimidazo[1,2-a]pyridine hydrobromide was added to 70 ml of a sodium hydrosulfide solution at room temperature, followed by stirring at 90° C. for 24 hours. After the reaction mixture was cooled, concentrated hydrochloric acid was added until the reaction mixture's pH became 3-4. The resulting precipitate was collected by filtration, washed with water and dried to yield 12.32 g (quant, yellow powder) of the desired product.
