실험 절차

A mixture of 4-(1-cyclohexyl-4-piperidyl)benzonitrile (0.68 g), thiosemicarbazide (0.58 g) and trifluoroacetic acid (3.5 ml) in toluene (7 ml) was stirred for 7 hours at 70° C. After being cooled to room temperature, the solvent was evaporated in vacuo. Then the residue was dissolved in tetrahydrofuran and poured into water. The solution was adjusted to pH 8 with 1N aqueous sodium hydroxide. The resulting precipitate was collected by filtration and washed with water and isopropyl ether to give 5-[4-(1-cyclohexyl-4-piperidyl)phenyl]-1,3,4-thiadiazol-2-amine trifluroacetate (0.80 g).
