From the reaction of the 2,5-dialkylbensoquinones (Ia or b) with sodium azide in sulphuric acid at 40-50°. Caronna (1) obtained products which he suggested were imines (II: R, R, R = alkyl, alkyl, hydrogen). Recently, Folkers. Misiti and Moore (2) reacted the benzoquinones (Ia -d) and t-methylnaphthoquinone (Ig) with the same reagents

## 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
In the asymmetric unit of the title compound, C 9 H 8 N 2 O 2 , there are two crystallographically independent molecules, each of which forms a dimer, via N-HÁ Á ÁO hydrogen bonds, with an inversion-related molecule.
