| Abstract: | Novel 5-Methyl-3-substituted-1,2,4-triazolo3,4-b]benzothiazoles were synthesized from o-methylaniline to 5 with various aromatic carboxylic acids. The yielded product 6a-e was investigated with X-ray crystallographic, 1HNMR, MS and IR techniques. Compound 6e, C24H16N4S,Mi=392.69, crystallized in the triclinic space group PI with unit cell parameters a=9.713(3), b=14.645(4), c=15.641(3)Å, α=113.17(2), β=90.11(2), γ=109.29(2)°,V=1908.1(7) Å3, Z=4, Dm=0.687Mgm-3. |
