实验步骤: A mixture of 4.0 g of cis-2-phenylcyclopentylamine hydrochloride, M.P. 205°-206° C. and 5.0 ml of O-methylcaprolactim was allowed to stand at room temperature for 6 days with occasional stirring. A few drops of ethanol were added to maintain a stirrable slurry, after which the mixture was cooled. The resulting solid was washed with ether and recrystallized from acetone/methanol to give the desired product, M.P. 181.5°-183.5° C. (dec.). to maintain a stirrable slurry after which the mixture was cooled The resulting solid was washed with ether recrystallized from acetone/methanol

反应条件: temp:-20.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of 15.0 g of α-methyl-ρ-phenethylbenzylamine hydrochloride and 25 ml of O-methylcaprolactim is stirred into a slurry and allowed to stand at room temperature for 4 days with occasional stirring. Small portions of absolute ethanol are added to keep the slurry stirrable. The mixture is then cooled to -20° C., the precipitate is collected, washed with small portions of absolute ether and recrystallized from a mixture of acetone-methanol to yield 15.7 g (76% yield) of the desired product, M.P. 230°-231.5° C. the precipitate is collected washed with small portions of absolute ether recrystallized from a mixture of acetone-methanol

实验步骤: To 200 ml of methanol is added 3.6 g (0.1 mole) of gaseous HCl followed by 12.7 g (0.1 mole) of O-methylcaprolactam and then 10.6 g (0.1 mole) of thiocarbohydrazide. After heating at reflux for 2 hours, the mixture is allowed to cool to room temperature and is refrigerated. The solid product is recrystallized twice from methanol/ethyl acetate, affording 13.4 g of 4-amino-5-(5-aminopentyl)-4H-1,2,4-triazole-3-thiol hydrochloride. m.p. 192°-194° C. After heating at reflux for 2 hours The solid product is recrystallized twice from methanol/ethyl acetate
