Procedure

6.291 g (23.921 mmol) of 5-fluoro-3-iodo-1H-pyrazolo[3,4-b]pyridine and 8.573 g (26.313 mmol) of caesium carbonate were put in DMF (10 ml) and then 5.00 g (26.313 mmol) of 2-(bromomethyl)-3-fluoropyridine dissolved in DMF (20 ml) was added dropwise. The mixture was stirred overnight at RT. Then it was left to cool and was poured into 200 ml water. A precipitate was filtered off with suction, it was washed with water and dried overnight under high vacuum. 6.28 g (70% of theor.) of the title compound was obtained.
