    Notes: Preparation of Carboxylic Acid Derivatives of Oxalic Acid-N1-acyl AmidrazonesThe synthesis of oxalic acid ethylester-N1-acyl amidrazones 1 is described. The amidrazonecarboxylates 1 were converted to the oxalic acid-N1-acyl amidrazones 2 and to the corresponding carboxamides 3 and hydrazides 4, which yield [5-amino-1,3,4-oxadiazol-2-yl]-N1-acylamidrazones 5.
