Abstract

Durch Umsetzung der 5‐Aryloxazole 2a–e sowie der substituierten Vertreter 8a–c und 10 mit 4‐Phenyl‐4__H__‐1,2,4‐triazol‐3,5‐dion (3) lassen sich die neuen 7‐Aroyl‐1__H__,7__H____s__‐triazolo[1,2‐a]‐s‐ triazol‐1,3(2__H__)‐dione 5a–e, 9a–c und 11 herstellen. Die Struktur wird aus den ^13^C‐NMR‐spektroskopischen Daten von 5b, 9a und 11 abgeleitet. Der Mechanismus der Bildung wird kurz diskutiert.

## Abstract Pentadeuteriophenyl clobazam 5 was synthesized in essentially quantitative isotopic purity, and characterized by ^1^H‐NMR and mass spectroscopy. The title compound was found to be ≥98% pure by HPLC, and its retention time (t~R~ 6.17 min) was less than that of an authentic clobazam stand
