Improvements in the synthesis of urazoles via a proposed transcarbamylation reaction are reported. Some experimental evidence for a transcarbamylation mechanism as indicated by the formation of identified intermediate products is shown. 13C n.m.r. studies on 1-phenyl-4-anilinourazole have settled the controversy on the structure of Pinner's compounds by establishing that they are 1,2,4-triazoles rather
