Three-component reactions of ethyl 1-phenyl-3-trifloromethyl-5-[(triphenylphosphanylidene)amino]-4-carboxylate (iminophosphorane 2) with aromatic isocyanate and piperazine derivatives produced novel 1,4-[6,6'-(3-trifluoromethyl-pyrazolo[3,4-d]pyrimidinyl)]piperazines in the presence of EtONa in 55%~87% yields. The structures of synthetic compounds were confirmed by 1H NMR, IR, MS techniques and elemental analysis.

Key words: piperazine, pyrazolo[3,4-d]pyrimidine, multi-component reaction, synthesis
