The methaqualone analog described here was submitted as an exhibit to the Drug Enforcement Administration North Central Laboratory by a State laboratory; the sample was initially thought to be methaqualone free-base 1. Mass spectrometry and proton NMR spectroscopy (1-dimensional) were used to identify the analog. The results showed that the structural analog contained a second methyl group in the molecule, relative to methaqualone, and that the group was attached to the existing methyl-substituted penyl ring. When the proton 2-dimensional NMR techniques were applied, specifically the homonuclear shift correlation spectroscopy and 2-D NOE, the precise location of the methyl group in this unknown methaqualone analog was established and shown to have the structure 2. 9 figures, 2 tables, and 11 references
