title: Major metabolites of zolpidem: expeditious synthesis and mass spectra.
abstract: An expeditious route to the two major metabolites of Zolpidem-and readily applicable to the synthesis of the drug-was established via a cyclization reaction between a 2-aminopyridine and a suitable alpha-bromoacetophenone. The structures of the target compounds were confirmed from a 2D (1)H-(15)N NMR correlation. Their mass spectra contribute to a reliable toxicological identification of the drug in the case of drug-facilitated crimes.
