    Abstract: In the present invention there is disclosed a process for preparing carboxylic acid of the general formula II, in which the substituents Re1 through Re5 have specific meaning, by reacting enamine with acid chloride and further by reacting the resulting intermediate with malonamic acid ester in the presence of a base. Subsequently the obtained compound is protected on the hydroxy position by treatment thereof for example with methyl chloride. The resulting compound then reacts with an alkali metal base and subsequently with 3-alkoxyacryloyl compound and the formed intermediates is reacted with a catalytic amount of acid in order to close a ring and finally the resulting acid is reacted with a halogenating agent.
