Holy Crap!!!!
What a weird coincidence. I just started to synthesize a new series of compounds last week and I downloaded a paper because I was interested in two of the reactions described in there. So during this week I am following the procedures described in that paper. Now I am reading Shane's post and I just went to check the chemical structure of Zolpidem, and, OMG, OMG, OMG it turns out that the paper I downloaded last week is the one where the synthesis of Zolpidem was described for first time.
That is just an amazing coincidence.
BTW, that paper describes how to synthesize Zolpidem and derivatives and the very first structure-activity results.
