Reaction of 2-chloronicotinonitrile (I) with 1-methyl-3-phenylpiperazine (II) gives 2-(4-methyl-2-phenyl-1-piperazinyl)-3-pyridinecarbonitrile (III), which is hydrolyzed to the carboxylic acid, which is reducted to the hydroxymethyl derivative (IV). Cyclization of (IV) in concentrated sulfuric acid at 20-35 C gives the title compound after 2 h and treatment with ammonia.
