It has a role as an EC 2.1.1.6 (catechol O-methyltransferase) inhibitor, an antiparkinson drug, a central nervous system drug and an antidyskinesia agent. It is a monocarboxylic acid amide, a nitrile, a member of catechols and a member of 2-nitrophenols.
Manufacturing Process
N,N-Diethyl-2-cyano-3-(3,4-dihydroxy-5-nitrophenyl)acrylamide (2-
Propenamide, 2-cyano-3-(3,4-dihydroxy-5-nitrophenyl)-N,N-diethyl).
A solution containing 1.83 g of 3,4-dihydroxy-5-nitrobenzaldehyde, 1.5 g of
N,N-diethylcyanoacetamide and catalytic amount of piperidine acetate in 40
ml of dry ethanol was refluxed over night. After cooling the solvent was
evaporated in vacuo and the residue was recrystallized from waterdimethylformamide. Yield of desired product was 2.23 g (73%), melting point
153°-156°C.
