Abstract
Abstract Novel 5-methyl-3-substituted-1,2,4-triazolo[3,4-b]benzothiazoles were synthesized from o -methylaniline to 5 with various aromatic carbonic acids. The yielded product 6a – e were confirmed by Elemental Analyses, NMR, MS, IR spectra and 6e was investigated with X-ray crystallography. Compound 6e , C 24 H 16 N 4 S, Mr=392.69, crystallized in the triclinic space group P 1 with unit cell parameters a =9.713(3) A, b =14.645(4) A, c =15.641(3) A, α =113.17(2)°, β =90.11(2)°, γ =109.29(2)°, V =1908.1(7) A 3 , Z =4, D m =1.366 Mgm −3 .
