    IPC: C07D231/20

    Abstract: The invention relates to a method for producing 1-substituted 5- and/or 3-hydroxypyrazoles of formula wherein R1 represents C1-C6-alkyl,C2-C6-alkenyl, C2-C6-alkinyl, C3-C6-cycloalkyl or C1-C4-alkoxy, whereby these groups can be substituted by halogen, C1-C4-alkoxy, phenoxy, C1-C6-alkoxycarbonyl, or a cyclic ring system with 3-14 ring atoms, by reacting a 3-alkoxyacrylic acid alkyl ester for formula wherein R2, R3 independently means C1-C6-alkyl or C3-C6 cycloalkyl, with a hydrazine or formula wherein R1 has the above cited meaning, a) at a pH value of 6-11 to form 5-hydroxypyrazoles of formula or b) at a pH value of 11-14 to form 3-hydroxypyrazoles of formula (II).
