Reaction Steps

2,5-Dibromopyridine (1.30 g) was heated with 4,4-difluoropiperidine (2 g) in dimethylacetamide (4 ml) at 120° C. for 24 h, then at 150° C. for 8 h. The solution was allowed to cool, then poured into water (30 ml). The aqueous phase was extracted with ether (×3) and the combined extracts washed with water, dried over magnesium sulfate, filtered and evaporated. Purification by column chromatography gave the product as a colourless oil (0.70 g).
