실험 절차

5 g of 4-[1-(1,2,3-triazolyl)methyl]benzonitrile is dissolved in 100 ml of tetrahydrofuran and combined at -60° with 20 ml of 1.5-molar solution of lithium diisopropylamide in tetrahydrofuran, stirred for 0.5 hour, further stirred for 1 hour at -70° with 2.4 g of cyclopentanone, and heated to 25°. Then the mixture is combined with water, extracted three times with ethyl acetate, washed with water, dried over sodium sulfate, and concentrated to dryness under vacuum, thus obtaining 7.1 g of crude 4-[1-hydroxycyclopent-1-yl-1-(1,2,3-triazolyl)methyl]benzonitrile.
