Abstract

Procedure for the preparation of benzofuran derivatives, of general formula: **(See formula)** wherein R1 represents a hydrogen atom or an alkyl radical and each of the symbols R2 and R3, individually, represents a hydrogen atom, a halogen atom or an alkyl radical, with the exclusion of the meaning R1 = R2 = R3 = H, each of the alkyl radicals contains from 1 to 6 carbon atoms, straight or branched, characterized in that the compounds of formula **(See formula)** to a nitration by means of nitric acid concentrated in acetic acid.
