By taking into account the important biological activity of the aminosulphonyl-phenoxyacetic acids, we considered useful to capitalize a series of seven previously syntetised hydrazides by their condensation with arylaldehydes. The reaction was carried out in ethanol medium using acetic acid as a catalyst. The obtained products were purified by recrystallisation in organic solvents (ethanol especially) and characterised by elemental analysis data, IR spectral measurements and melting points.
