General description

1-(Diphenylmethyl)piperazine is an intermediate during drug synthesis. It has been reported to be formed during the oxidative metabolism of cinnarizine (CZ) [1-(diphenylmethyl)-4-(3-phenyl-2-propenyl)-piperazine] in rat liver microsomes. It reacts with quinone in acetonitrile, followed by oxidation with an alkaline potassium ferricyanide, to afford 4-amino-3,6-di(tert-butyl)-o-benzoquinones.

Application

1-(Diphenylmethyl)piperazine [N-(Diphenylmethyl)piperazine] may be used for the synthesis of 2-nitro-3,4,4-trichloro-1-(propylthio)-1-[4-(diphenylmethyl)piperazin-1-yl]-1,3-butadiene and 2-nitro-3,4,4-trichloro-1-(octadecylthio)-1-[4-(diphenylmethyl)piperazin-1-yl]-1,3-butadiene.

In order to explore the antiproliferative effect associated with the piperazine framework, several 1-benzhydrylpiperazine derivatives 8(a-d), 9(a-d) and 10(a-h) were synthesized. Variation in the functional group at N-terminal of the piperazine led to three sets of compounds, bearing the sulfonyl
