Abstract

Procedure for obtaining thiophenecarboxylic acid derivatives, of formula I, ** (See formula) ** wherein RI1 is alkyl of 1 to 4 carbon atoms, R2 is hydrogen, chlorine, or alkyl or alkoxy of 1 to 3 carbon atoms, and R3 is hydrogen, chlorine, bromine, or alkyl or alkoxy of 1 to 3 carbon atoms. carbon, or, when R2 signifies hydrogen, can also be fluorine or trifluoromethyl, characterized in that a compound of formula II is oxidized, ** (See formula) ** where RI1, R2 and R3 have the meanings indicated above.
