by copper mediated N-arylation of 1-phenyl-1H-tetrazol-5(4H)-one with aryl boronic acids, o-R1C6H4B(OH)2 where R1 = H, OMe, Cl, CF3, Br, CCH. The 1,4-diaryl tetrazol-5-ones substituted with OMe, Cl, CF3, Br underwent thionation with Lawesson’s reagent to yield the corresponding 5-thio derivatives. The 1-(2-bromophenyl)-4-phenyl-1H-tetrazole-5(4H)-thione so obtained was subjected to lithiation/protonation
