Diaminofurazan (1) was synthesized from glyoxal (2) by an improved two-step procedure. The N-mono-arylmethyl derivatives 4a-e and N-N'-diarylmethyl derivatives 5a-e of 1 were prepared in good yields by reductive alkylation with the corresponding aryl aldehydes.

uryl)methylthio] ethylamino]furazan (1) containing carbonyl groups joined to the amino functions linked to the furazan system have been synthetized and investigated for their H2‐antagonist properties on the isolated guinea pig right atrium. The presence of the carbonyl group lowers the activity in respect to the corresponding leads. The decrease in activity is only by 1‐2 orders of magnitude in the
