Article abstract of DOI:10.1007/BF00809770

Syntheses of some substituted 7-hydroxy-5H-1,3,4-oxadiazolo<3,2-a>pyrimidin-5-ones (3) and their 7-methoxy (4), 7-chloro (5) and 7-azido (6) derivatives are described. 2-Phenyl-N,N'-bis(3-tolyl)propanediamide (8) was obtained, instead of the expected tria
