nucleophilic aromatic subsitution (SNAr) reactions between various nucleophiles and electrophiles. The mild reactionconditions facilitate a broad functional group tolerance that can be utilized for subsequent derivatization for the synthesis of pharmaceutically relevant building blocks. The use of only equimolar amounts of all reagents and water as reaction solvent reveals the greenness and sustainability

IC50 in range 2.3–20 µM and selectivity towards acetylcholinesterase, while being inactive towards butyrylcholinesterase. Structure-activity relationship analysis revealed the influence of N,N-diarylpiperazine moiety and the linker connecting two pharmacophores on the inhibitory activity. Kineticstudies on the two most active compounds 7g and 8g (IC50 = 2.3 and 4 µM, respectively) revealed mixed type
