    • Process for preparing a compound of the formula (I) in which Het is a bicyclic unsaturated heterocyclyl bonded to the rest of the molecule via a carbon atom, where the ring not bonded directly to the rest of the molecule is substituted by R 1 and R 2 , R 1 and R 2 are each independently H, C 1 -C 8 -alkyl, halogen, polyhalo-C 1 -C 8 -alkoxy, polyhalo-C 1 -C 8 -alkyl, C 1 -C 8 -alkoxy, C 1 -C 8 -alkoxy-C 1 -C 8 -alkyl, or C 1 -C 8 -alkoxy-C 1 -C 8 -alkoxy, where R 1 and R 2 are not both H, and R 3 is C 1 -C 8 -alkyl, which is characterized in that a) a compound of the formula ( II) in which Het, R 1 and R 2 are each as defined above and X is Br, I, triflate, tosylate or mesylate is reacted with prop-2-yn-1-ol to give a compound of the formula (III) and b) the compound of the formula (III) is reacted with an alkyl-metal compound in which "alkyl" is as defined above for R 3 to give a compound of the formula (I).
    • 制备其中Het是通过碳原子与分子的其余部分键合的双环不饱和杂环基的式(I)化合物的方法,其中不与分子的其余部分键合的环被R 1和R 2,R 1和R 2各自独立地为H,C 1〜 C 8 - 烷基,卤素,多卤代-C 1 -C 8 - 烷氧基,多卤代-C 1 - C 1 -C 8 - 烷基,C 1 -C 8 - 烷氧基,C 1 -C 8 - 烷基,C 1 -C 8 - 烷氧基-C 1 -C 8 - 烷基或C 1 -C 8 - 烷氧基 -C 1 -C 8 - 烷氧基,其中R 1和R 2不都是H,R 其特征在于a)式(II)化合物,其中Het,C 1 -C 6烷基,C 1 -C 6烷基, R 1和R 2各自如上所定义,X是Br,I,三氟甲磺酸酯,甲苯磺酸酯或甲磺酸酯与丙-2-炔-1-醇反应,得到 一种化合物 (III)和b)使式(III)的化合物与烷基金属化合物反应,其中“烷基”如上述R 3所定义,得到式( 一世)。
