Reaktionsschritte
Alternatively, 3-bromo-2-chloropyridine may be used as shown in Scheme VIII. Thus, 3-bromo-2-chloropyridine (27) is heated with piperazine to provide 1-(3-bromopyridin-2-yl)piperazine (28), followed by Suzuki coupling of the phenyl moiety to provide the phenylpiperazine intermediate (25).
