実験手順

7.6 g of crude 4-[1-hydroxycyclohex-1-yl-1(1,2,3-triazolyl)methyl]benzonitrile is dissolved at 0° in 50 ml of dichloromethane and stirred at 0° for 1 hour with 22.7 ml of thionyl chloride. Then the mixture is concentrated to dryness under vacuum, dissolved in 50 ml of dichloromethane, stirred with 30 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, thus obtaining 2.6 g of 4-[1-cyclohexylidene-1-(1,2,3-triazolyl) methyl]benzonitrile as the free base, 132°-133° C.
