  • Patent number: 5100890
    Abstract: Arylmethylazoles of the formula I ##STR1## in which Aryl is (substituted) phenyl or naphthyl;Z is CH or N;R.sup.1 and Q are H or alkyl;R.sup.2 is H, alk(en)yl or alkynyl;R.sup.3 and R.sup.4 are H, alkyl or other hydrocarbons; orR.sup.3 and R.sup.4 together are a--(CH.sub.2).sub.2-11 chain or a bridged--(CH.sub.2).sub.4-5 chain,and their acid addition salts, stereoisomers and optically active enantiomers possess outstanding antimycotic and antidepressant activity.They are obtained, inter alia, from arylmethylazoles II ##STR2## which are reacted with a strong base and then with a carbonyl compound III O.dbd.CR.sup.3 R.sup.4 ; thereafter, the product is reacted with the protic acid or with an alkyl halide IV R.sup.2 Hal.If desired, the products are converted to the acid addition salts, or the stereoisomers or optically active enantiomes are resolved.
