Abstract

A metabolite of Aripiprazole (1), 7-[4-[4-(2, 3-dichloro-4-hydroxyphenyl)-1-piperazinyl] butoxy]-3, 4-dihydro-2 (1H)-quinolinone (2), was prepared by the coupling reaction of 1-(4- benzyloxy-2, 3-dichlorophenyl)-piperazine (11) with 7-(4-chlorobutoxy)-3, 4-dihydro-2 (1H)- quinolinone (16). The palladium-catalyzed amination of contiguous tri-and tetra-substituted benzenes with piperazine derivatives was investigated. The key intermediate 11 was ...
