The invention relates to a new preparation method of derivatives of substituted 2-arylaikanoic acids. The compounds are used for the preparation of histaminically active compounds and antiphlogistics. The compounds are prepared by reaction of suitably substituted a-halogen acetophenones with orthoformates with catalysis by mineral and Lewis acids.
