实验步骤: 3-Cyclohexylpropionitrile (181 g) and 120 g of thiosemicarbazide were dissolved in 40 ml of trifluoroacetic acid, followed by stirring at a bath temperature of 70° to 80° C. for 4 hours. The reaction mixture was poured into ice-water, and 500 ml of concentrated aqueous ammonia was added thereto, followed by stirring at room temperature for 1.5 hours. The resulting precipitate was collected by filtration and washed with successive, small amounts of ethanol and diethyl ether to obtain 197 g of the titled compound. was added by stirring at room temperature for 1.5 hours The resulting precipitate was collected by filtration washed with successive, small amounts of ethanol and diethyl ether
