Participants

Reaction Steps

Solution of 6-bromo-2-carboxypyridine (3 g, 16.1 mmol) was dissolved in dichloromethane (100 mL). (Triphenylphosphoranylidene)acetaldehyde (4.9 g, 16.1 mmol) was added and obtained mixture was stirred at room temperature for 5 hrs. Dichloromethane was partially evaporated (to the volume about 50 mL) and reaction mixture was applied on chromatography column (SilicaGel 60) Products were eluted with dichloromethane. Fractions containing product were combined and evaporated to give 2.3 g of white powder (Yield 67%).
