2-Naphthalenecarboxaldehyde → HCID 43609714, compound

Participants

Reaction Steps

To a solution of tetrahydro-2H-pyran-4-amine (500 mg) in chloroform (5 mL), 2-naphthoaldehyde (772 mg) was added and the resulting mixture was stirred for 30 minutes. Sodium (triacetoxy)borohydride (1.57 g) was added and the resulting mixture was stirred for 4 hours at room temperature. To the reaction mixture, an aqueous solution of 1 M sodium hydroxide was added and after stirring the resulting mixture, the chloroform layer was separated and dried over anhydrous sodium sulfate. After filtering off the desiccant, the solvent was distilled off under reduced pressure and the resulting residue was purified by column chromatography (silica gel cartridge; chloroform/methanol=100:0 to 97:3) to give the titled compound (821 mg).
