実験手順
A solution of 8-bromomethyl-1,2-dihydro-1,1-dimethyl-2-oxonaphtho[2,1-b]furan-7-carbonitrile in N,N-dimethylformamide (3 ml) was treated with sodium 1,2,4-triazole (0.18 g) and the mixture was stirred at room temperature for 4 h, then treated with water (20 ml). The mixture was extracted twice with ethyl acetate and the combined extracts were dried and evaporated to dryness under reduced pressure. The residue was purified by flash chromatography using methanol:ethyl acetate, 1:99 v/v, as eluant to give 1,2-dihydro-1,1-dimethyl-2-oxo-8-(1H-1,2,4-triazol-1-ylmethyl)naphtho(2,1-b)-furan-7-carbonitrile, m.p. 198°-198° after recrystallisation from a mixture of ethyl acetate and cyclohexane.
