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.
该发明涉及一种新的制备取代2-芳基丙酸衍生物的方法。这些化合物用于制备组胺活性化合物和抗炎药。这些化合物通过适当取代的α-卤代苯乙酮与正甲酸酯在矿物酸和路易斯酸的催化下反应制备而成。
