摘要：
5-Methyl[1,2,4]triazolobenzothiazole 2 has been synthesized by the condensation of 2-hydrazino-4-methylbenzothiazole 1 with formic acid. Corn-pound 2 with N-methylaniline and formaldehyde results in Mannich base 8. The styryl derivative II in cis-form is obtained from 10 with anisaldehyde. A new tetracyclic system phenylpyrrolotriazolo-benzothiazole 13 is synthesized from 10 by the action of phenacyl bromide.
