F. Kerrigan et al., SYNTHESIS OF ARYLPIPERAZINES VIA PALLADIUM-CATALYZED AROMATIC AMINATION REACTIONS OF BROMOARENES WITH N-TERT-BUTOXYCARBONYLPIPERAZINE, Tetrahedron letters, 39(15), 1998, pp. 2219-2222
Reaction of a series of bicyclic bromoarenes with N-tert-butoxycarbony
lpiperazine (N-Boc-piperazine) under palladium-calalysed coupling cond
itions followed by routine removal of the Boc group with trifluoroacet
ic acid in dichloromethane gave the corresponding arylpiperazines in m
oderate to good yield. (C) 1998 Elsevier Science Ltd. All rights reser
