Hydrogen chloride-ethyl acetate → HCID 70873526, compound

Participants

Reaction Steps

2 N hydrogen chloride-ethyl acetate solution (20 ml) was added to an ethanol solution (20 ml) of 5-methoxymethoxy-2-(4-trifluoromethoxybenzyloxymethyl)pyridine (2.3 g) and stirred at room temperature for 16 hours. The reaction mixture was concentrated under reduced pressure and a sodium hydrogen carbonate aqueous solution was added to the residue, followed by extraction with ethyl acetate. The organic layer was washed with water and a saturated sodium chloride aqueous solution and dried over sodium sulfate. The result was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane:ethyl acetate=4:1→2:1). The result was concentrated to dryness under reduced pressure to afford the title compound as a white solid (2.4 g).
