Reaction Steps

A mixture of 3-(4-methylphenyl)furane-2-carbaldehyde (1.0 g), hydroxylamine hydrochloride (560 mg), and sodium acetate (660 mg) in 60% aqueous ethanol (10 ml) was stirred for one and half hours at 65° C. The mixture was concentrated in vacuo. The residue was dissolved in a mixture of ethyl acetate and aqueous sodium bicarbonate solution. The organic layer was washed with brine, dried, and concentrated in vacuo to give a yellow solid. A mixture of the solid and sodium acetate (56 mg) in acetic anhydride (10.5 ml) was refluxed for 5 hours and then evaporated in vacuo. The residue was purified by column chromatography on silica gel (elution by n-hexane/ethyl acetate=15/1) to yield 3-(4-methylphenyl)furane-2-carbonitrile (884 mg) as a yellow oil.
