実験手順

7.1 g of crude 4-[1-hydroxycyclopent-1-yl-1-(1,2,3-triazolyl)methyl]benzonitrile is dissolved at 0° in 50 ml of dichloromethane and stirred with 24 ml of thionyl chloride for 1 hour at 0°. Then the mixture is concentrated to dryness under vacuum, dissolved in 50 ml of dichloromethane, stirred with 32 ml of triethylamine for 2 hours, diluted with water, extracted three times with ethyl acetate, washed with water, dried over sodium sulfate, concentrated to dryness under vacuum, and chromatographed on silica gel with hexane/ethyl acetate, yielding 2.1 g of 4-[1-cyclo-pentylidene-1-(1,2,3-triazolyl)methyl]benzonitrile as the free base, 108-109°.
