${circo}-페닐렌디아민(3)을 출발물질로 하여 4단계를 거쳐 {alpha}-arylhydrazonoacylazide(7)를 합성하였다. 얻어진 {alpha}-arylhydrazonoacylazide(7)는 디메틸슬폭시드 용액에서 hydrazone imine형과 diazenyl enamine형으로 존재하는데 이들 사이의 토오토메리 현상을 ^1H-NMR 스펙트럼 데이타에 의하여 측정된 토오토머 비로서 고찰하였다. {alpha}-arylhydrazonoacylazide(7)를 벤젠용매에서 환류시켜 1-aryl-3-quinoxalinyl-1,2,4-triazol(8)을 합성하였다.$
${alpha}-Arylhydrazonoacylazide(7) was synthesized starting from {circo}-phenylenediamine(3) in four steps. The tautomeric behavior of {alpha}-arylhydrazonoacylazide(7) between the hydrazone imine and diazenyl enamine forms in the dimethyl sulfoxide solution was investigated on the basis of the tautomer ratio determined by the ^1H-NMR spectral data. The 1-aryl-3-quinoxalinyl-1,2,4-triazol(8) was synthesized from {alpha}-arylhydrazonoacylazide(7) by refluxing in benzene.$
