What are the applications of Application

Fenpiverinium Bromide is an anti-cholinergic and anti-spasmodic

Manufacturing Process

17.5 g diphenylpiperidine ethyl acetonitrile, prepared from sodium amide and 2-piperidinoethyl chloride (D.B. Patent No. 710,227) was heated to reflux with 35 g KOH, 70 ml ethanol and 2 ml water for 6 hours. On cooling rich white crystals dropped. They was filtered off, washed with water to neutral and dried. Then the product was recrystallized from ethanol. Yield of diphenylpiperidine ethyl acetamide 15 g. MP: 186°-187°C.
10 g diphenylpiperidine ethyl acetamide was mixed with 42 g of 17% solution methyl bromide in benzene and 60 ml isopropanol and heated to reflux on a steam bath for 0.5 hour. The solvent was distilled in vacuum to dryness, dissolved in 100 ml of water and the very muddy solution was through a coal filtered. The clear filtrate was distilled off to dryness. Fenpiverinium bromide was light dissolved in water and had neutral reaction.
