Abstract

Process for the preparation of furazan derivatives of the general formula i, ** (see formula) ** In which R1 means hydrogen or a lower alkyl group, and R2 means a lower alkyl group, which occupies the ortho or meta position, Characterized in that a compound of the general formula ii is hydrolysed ** (see formula) ** In which R1 and r2 have the significance indicated under formula i and X means an acyl radical of an organic acid, especially a carboxylic acid radical or the radical of a monofunctional carbonic acid derivative.
