Identification and synthesis of a methylated catechol metabolite of glutethimide isolated from biological fluids of overdose victims

Urine samples from victims severely intoxicated by glutethimide were hydrolyzed enzymatically. TLC, GLC, and mass spectral analyses revealed a methylated catechol metabolite of the parent drug. Two synthetic pathways are described for the preparation of 2-ethyl-2-(3-methoxy-4-hydroxyphenyl)glutarimide and 2-ethyl-2-(3-hydroxy-4-methoxyphenyl)glutarimide. Comparisons of GLC and mass spectral data to a compound isolated from the body fluids of glutethimide overdose victims conclusively identified a new 3-methoxy-4-hydroxyphenyl metabolite of glutethimide in humans.
