Abstract

Process for the preparation of 3- (phenyl substituted) pyrrole derivatives with the general formula (I) ** (See formula) ** wherein X is hydrogen, halogen, nitro or lower alkoxy; And it is halogen, nitro or lower alkoxy; R1 and R2 are hydrogen, lower alkyl or esterified carboxyl; R3 is hydrogen or halogen; provided that at least one of R1, R2 and R3 is taken up by hydrogen, characterized in that it comprises the operations of decarboxylating, heating, a compound having the general formula (II) ** (See formula) ** where X and Y are the same, defined above; R4 and R5 are hydrogen, lower alkyl, esterified carboxyl or carboxyl; R6 is hydrogen, halogen or carboxyl; provided that at least one of R4, R5 and R6 is taken by carboxyl or esterified carboxyl to obtain a compound I.
