Reactions of methyl(ethyl) N-(2-cyanophenyl)carbamates with sodium azide in dimethylformamide at 80-90°C in the presence of anhydrous CdCl2 afforded the corresponding N-arylcarbamates with a 1,2,3,4-tetrazole fragment. The acylation of methyl N-[2-(1H-1,2,3,4-tetrazol-5-yl)phenyl]carbamate with acetic anhydride followed by the condensation of the obtained N-acyl derivative with thiophene-2-carbaldehyde in the KOH methanol solution led to the formation of methyl N-(2-{1-[3-(2-thienyl)-2-propenoyl]-1H-1,2,3,4-tetrazol-5-yl}phenyl)carbamate. The reaction of cyclohexyl N-(4-aminophenyl)carbamate with a triethyl orthoformate and sodium azide in glacial AcOH yielded cyclohexyl N-[4-(1H-1,2,3,4-tetrazol-1-yl)phenyl]carbamate.
