Wasn't the last "R-MDMA" actually Para-Tolyl-Cyclopropylamine, AKA 4-Methyl-Tranylcypromine? In other words, a drug clinically used as an irreversible MAOI modified to act as a serotonin releasing agent?
Holy fuck, do these people actually have souls?
As for this substance, I don't see why they would go with Phen-DI-Metrazine. If for some reason they can't make a regular Phenmetrazine, it seems to me that the more promising route to follow would be to skip the the N-Methyl, and instead elongate the original methyl group into a propyl chain, sacrificing the releasing agent action but making the resulting molecule (MethyleneDioxyPhenPropAzine ?) bulky enough to act as a dopamine reuptake inhibitor. At this point, this is all pure conjecture of course.
