Abstract

Improvements in the subject of main patent no. 367,838, for "Procedure for the preparation of new heterocyclic carboxylic acids", essentially for the preparation of 2,3-dihydro-5- (2-methylene-valeryl) -6,7-dimethyl-benzofuran-2-carboxylic acid, thus as its salts with inorganic or organic bases, characterized in that a compound of the general formula I ** (See formula) ** in which Am means the radical of a secondary organic base decomposes under cleavage of a secondary organic base and the carboxylic acid obtained is eventually transformed with an inorganic or organic base into a salt.
