実験手順: A mixture of 2-hydroxymethyl-7-methoxybenzofuran (300 mg), sodium cyanoborohydride (796 mg) and zinc iodide (809 mg) in dichloroethane (10 ml) was stirred for 2 hours at ambient temperature and then refluxed overnight. Chloroform and water were added to the reaction mixture, and the separated organic layer was washed with brine, dried over magnesium sulfate and evaporated in vacuo. The residue was purified by flash chromatography (n-hexane:ethyl acetate=15:1, v/v) to give 7-methoxy-2-methylbenzofuran (95 mg). refluxed overnight the separated organic layer was washed with brine dried over magnesium sulfate evaporated in vacuo The residue was purified by flash chromatography (n-hexane

実験手順: A mixture of 2-ethoxycarbonyl-7-methoxybenzofuran (360 mg), lithium borohydride (36 mg) in tetrahydrofuran (4 ml) was stirred at ambient temperature overnight and then for 8 hours at 50° C. Saturated ammonium chloride solution was added to the reaction mixture, and the solution was extracted with ethyl acetate. The extract was washed with saturated ammonium chloride solution and brine, dried over magnesium sulfate and evaporated in vacuo. The residue was purified by flash chromatography (n-hexane—ethyl acetate) to give 2-hydroxymethyl-7-methoxybenzofuran (310 mg). for 8 hours at 50° C the solution was extracted with ethyl acetate The extract was washed with saturated ammonium chloride solution and brine dried over magnesium sulfate evaporated in vacuo The residue was purified by flash chromatography (n-hexane—ethyl acetate)
