Reaction Steps

To 2-(pyridin-4-yl)pyrazolo[1.5-a]pyrimidine (0.30 g) in 15 mL chloroform was added dropwise a solution of 86 μL bromine in 1 mL chloroform. After 1.5 hours. at ambient temperature, the mixture was diluted with dichloromethane, washed with 10% aqueous potassium carbonate, dried over sodium sulfate, filtered, and evaporated to afford 386 mg (92% yield) product as a tan solid. MS showed a M+1 molecular ion of m/z 277.4 by positive APCI.
