Reaction Steps

Methyltriphenylphosphonium bromide (4.45 g, 12.5 mmol) was suspended in THF (25 mL) under dry nitrogen and treated with butyllithium (2.5 M in hexanes, 5 mL). After stirring the suspension for 30 minutes, 4-chloropyridine-3-carboxaldehyde (1.47 g, 10.4 mmol) was added. After 2 hours at ambient temperature, the reaction was diluted with hexanes, filtered, and evaporated. The material thus obtained was used directly without further purification or characterization.
