Abstract

Procedure for preparing substituted phenylalkylcarboxylic acids and their salts, particularly for preparing compounds of the general formula I **(See formula)** wherein R is hydrogen, a C1-4alkyl group or an arakyl group, R1 means hydrogen or a C1-4 alkyl group R2 stands for hydrogen or halogen R3 means a C1-6alkyl, aralkyl, aryl or aryloxy group, a group represented by the formula Arco, in which ar represents a phenyl or thienyl group characterized in that it comprises reacting compounds of the general formula II **(See formula)** where R, R2 and R-3 have the same meanings as indicated above, with thalic nitrate, in the presence of R1-OH, where R1 has the same meaning as indicated above and optionally transform the carbalkoxy group with hydrolysis and optionally transform the product into its salt.
