    摘要: Process for preparing a compound of the formula (I) in which R1 and R2 are each independently H, C1-C8-alkyl, halogen, polyhalo-C1-C8-alkoxy, polyhalo-C1-C8-alkyl, C1-C8-alkoxy, C1-C8-alkoxy-C1-C8-alkyl, or C1-C8-alkoxy-C1-C8-alkoxy, where R1 and R2 are not both H, and R3 is C1-C8-alkyl, which is characterized in that a) a compound of the formula (II) in which R1 and R2 are each as defined above and X is Br, I, triflate, toyslate or mesylate is reacted with prop-2-yn-1-ol to give the compound of the formula (III), b) the compound of the formula (III) is reacted with an alkyl-metal compound in which “alkyl” is as defined above for R3 to give a compound of the formula (I).
