1-[2-[3,5-substituted-1H-pyrazol-1-yl]acetyl]-4-piperidine-carbonitrile and -carbothiamide derivatives of formula 1B as intermediates in the preparation of fungicides for crop protection.
Preferred final compounds prepared therefrom are e.g. 4-[4-[4,5-dihydro-5-phenyl-3-isoxazolyl]-2-thiazolyl]-1-[[1H-pyrazol-1-yl]acetyl]piperidine derivatives.
1-[2-[3,5-取代的-1H-吡唑-1-基]乙酰基]-4-哌啶-甲腈和式 1B 的-羧噻嗪衍生物,作为制备作物保护用杀菌剂的中间体。
由此制备的优选最终化合物如 4-[4-[4,5-二氢-5-苯基-3-异恶唑基]-2-噻唑基]-1-[[1H-吡唑-1-基]乙酰基]哌啶衍生物。
