Looks like the N-methyl analog of fencamfamine
I believe yours is Zolpidem?
That's the thiophene analouge of meth. The name would be something like 1-(thiophene-2-yl)-2-methylaminopropane.
I'll edit this in a minute with a structure.
I'd prefer that. xDIt should be. As I said I am unfamiliar with the SAR of cocaine analogs but it would make sense that it would be active since the potency with methyl is 1 and ethyl is 60, even if it's a little too big it should still have some activity. Tacking on another methylene group doesn't usually kill activity completely except with N-alkyl PEAs.
And if it isn't active we can pretend it cocaethylene.
