ABSTRACT:
The invention relates to novel benzazole derivatives of the formula I ##STR1## wherein X is oxygen or sulphur, R.sub.1 is lower alkyl, lower alkenyl or cycloalkyl, optionally substituted R.sub.2 is hydrogen, and R.sub.3 is lower alkylthio or lower alkenylthio optionally substituted by esterified hydroxy, carboxy or esterified carboxy or R.sub.2 and R.sub.3 together are an additional bond of the C-N grouping, and R.sub.4 and R.sub.5 independently of one another are each hydrogen, lower alkyl or cycloalkyl radicals or taken together are a substituted or unsubstituted bivalent hydrocarbon residue of aliphatic character in which the carbon atoms of the chain may be interrupted by a heteroatom and their salts. The products are useful as anthelmintic effective agents. The products can be prepared according to methods known per se.
