Abstract: A process for preparing a compound of the formula Iwhere R1 and R2 are hydrogen or C1-C4-alkyl and R3 is C1-C10-alkyl, phenyl or C1-C4-alkyl-substituted phenyl, comprises reacting a compound IIwith a compound of the formula IIIwhere X is chlorine, bromine or iodine, in the presence of a Friedel-Crafts catalyst in one step to give a compound I.
