Ethyl orthoformate → HCID 58079761, compound

Participants

Reaction Steps

In ethanol (60 mL) was dissolved 6-bromonicotinaldehyde (2.00 g, 10.8 mmol). Triethyl orthoformate (5.37 mL, 32.3 mmol) and p-toluenesulfonic acid monohydrate (102 mg, 0.538 mmol) were added and the mixture was refluxed for 2 hours. The solvent in the reaction mixture was evaporated under reduced pressure, and a saturated aqueous sodium bicarbonate solution and water were added. Extraction with ethyl acetate, washing with saturated brine and drying over anhydrous sodium sulfate were performed. After filtration, the solvent in the filtrate was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=9/1) to give 2-bromo-5-(diethoxymethyl)pyridine (2.59 g, 92% yield).
