| abstract |
The invention relates to a process for preparing 5-aminobenzoylbenzofuran derivatives of formula (I), in which R1 represents hydrogen or an alkyl group and R2 represents hydrogen, an alkyl, alkoxy or dialkylaminoalkoxy group, by reduction of a 5-nitrobenzofuran derivative of formula (II) using a hydrogen transfer agent, in the presence of palladium-on-charcoal as catalyst and in an ether or an ether mixture as solvent. |
