6-Chloropyridine-3-carbaldehyde → HCID 117778379, compound

Participants

Reaction Steps

Triphenyl[4-(trifluoromethyl)benzyl]phosphonium bromide (6.4 g) and 6-chloropyridine-3-carboxaldehyde (1.8 g) were dissolved in ethanol (120 mL). To the solution, sodium tert-butoxide (1.2 g) was added at room temperature, and the mixture was stirred for 1 hour. The solvent was distilled off under reduced pressure, and ethyl acetate was added to the residue. The organic layer was washed with water and dried over sodium sulfate. The solvent was distilled off under reduced pressure, and the obtained residue was purified by silica gel column chromatography (Yamazen Corporation, elution solvent: hexane/ethyl acetate). The obtained solid was washed with hexane to obtain the title compound (0.89 g) (yield: 25%).
