Definition

ChEBI: Piritramide is a nitrile.

Manufacturing Process

A mixture of 84 parts of 3,3-diphenyl-3-cyanopropyl bromide, 41 parts of 4piperidino-4-piperidinecarboxamide, 64 parts of sodium carbonate, a small amount of potassium iodide and 1,200 parts of anhydrous toluene was stirred, and heated under reflux for 48 hours. At the end of this time the reaction mixture was allowed to cool to room temperature, and 500 parts of water were added. The resultant precipitate was removed by filtration, and triturated with diisopropyl ether. The crystalline material thus obtained was removed by filtration, and recrystallized from 320 parts of acetone, to give 1-(3,3diphenyl-3-cyanopropyl)-4-piperidino-4-piperidinecarboxamide, melting at about 149°C to 150°C.
