A Convenient Synthesis of Otherwise Inaccessible 3-Aminocinnoline-4-carboxylic Acid Derivatives

3-Amino-4-(2-nitroaryl)-2H-isoxazolin-5-ones, readily available by the sodium ethoxide catalysed cyclisation of amidoximes derived from ethyl 2-cyano-2-(2-nitroaryl)acetates, ring-close in the presence of sodium hydride to afford high yields of isoxazolo
